- Changes between 1.0.1 and 1.0.1a [xx XXX xxxx]
+ Changes between 1.0.1q and 1.0.1r [xx XXX xxxx]
+
+ *)
+
+ Changes between 1.0.1p and 1.0.1q [3 Dec 2015]
+
+ *) Certificate verify crash with missing PSS parameter
+
+ The signature verification routines will crash with a NULL pointer
+ dereference if presented with an ASN.1 signature using the RSA PSS
+ algorithm and absent mask generation function parameter. Since these
+ routines are used to verify certificate signature algorithms this can be
+ used to crash any certificate verification operation and exploited in a
+ DoS attack. Any application which performs certificate verification is
+ vulnerable including OpenSSL clients and servers which enable client
+ authentication.
+
+ This issue was reported to OpenSSL by Loïc Jonas Etienne (Qnective AG).
+ (CVE-2015-3194)
+ [Stephen Henson]
+
+ *) X509_ATTRIBUTE memory leak
+
+ When presented with a malformed X509_ATTRIBUTE structure OpenSSL will leak
+ memory. This structure is used by the PKCS#7 and CMS routines so any
+ application which reads PKCS#7 or CMS data from untrusted sources is
+ affected. SSL/TLS is not affected.
+
+ This issue was reported to OpenSSL by Adam Langley (Google/BoringSSL) using
+ libFuzzer.
+ (CVE-2015-3195)
+ [Stephen Henson]
+
+ *) Rewrite EVP_DecodeUpdate (base64 decoding) to fix several bugs.
+ This changes the decoding behaviour for some invalid messages,
+ though the change is mostly in the more lenient direction, and
+ legacy behaviour is preserved as much as possible.
+ [Emilia Käsper]
+
+ *) In DSA_generate_parameters_ex, if the provided seed is too short,
+ return an error
+ [Rich Salz and Ismo Puustinen <ismo.puustinen@intel.com>]
+
+ Changes between 1.0.1o and 1.0.1p [9 Jul 2015]
+
+ *) Alternate chains certificate forgery
+
+ During certificate verfification, OpenSSL will attempt to find an
+ alternative certificate chain if the first attempt to build such a chain
+ fails. An error in the implementation of this logic can mean that an
+ attacker could cause certain checks on untrusted certificates to be
+ bypassed, such as the CA flag, enabling them to use a valid leaf
+ certificate to act as a CA and "issue" an invalid certificate.
+
+ This issue was reported to OpenSSL by Adam Langley/David Benjamin
+ (Google/BoringSSL).
+ (CVE-2015-1793)
+ [Matt Caswell]
+
+ *) Race condition handling PSK identify hint
+
+ If PSK identity hints are received by a multi-threaded client then
+ the values are wrongly updated in the parent SSL_CTX structure. This can
+ result in a race condition potentially leading to a double free of the
+ identify hint data.
+ (CVE-2015-3196)
+ [Stephen Henson]
+
+ Changes between 1.0.1n and 1.0.1o [12 Jun 2015]
+ *) Fix HMAC ABI incompatibility. The previous version introduced an ABI
+ incompatibility in the handling of HMAC. The previous ABI has now been
+ restored.
+
+ Changes between 1.0.1m and 1.0.1n [11 Jun 2015]
+
+ *) Malformed ECParameters causes infinite loop
+
+ When processing an ECParameters structure OpenSSL enters an infinite loop
+ if the curve specified is over a specially malformed binary polynomial
+ field.
+
+ This can be used to perform denial of service against any
+ system which processes public keys, certificate requests or
+ certificates. This includes TLS clients and TLS servers with
+ client authentication enabled.
+
+ This issue was reported to OpenSSL by Joseph Barr-Pixton.
+ (CVE-2015-1788)
+ [Andy Polyakov]
+
+ *) Exploitable out-of-bounds read in X509_cmp_time
+
+ X509_cmp_time does not properly check the length of the ASN1_TIME
+ string and can read a few bytes out of bounds. In addition,
+ X509_cmp_time accepts an arbitrary number of fractional seconds in the
+ time string.
+
+ An attacker can use this to craft malformed certificates and CRLs of
+ various sizes and potentially cause a segmentation fault, resulting in
+ a DoS on applications that verify certificates or CRLs. TLS clients
+ that verify CRLs are affected. TLS clients and servers with client
+ authentication enabled may be affected if they use custom verification
+ callbacks.
+
+ This issue was reported to OpenSSL by Robert Swiecki (Google), and
+ independently by Hanno Böck.
+ (CVE-2015-1789)
+ [Emilia Käsper]
+
+ *) PKCS7 crash with missing EnvelopedContent
+
+ The PKCS#7 parsing code does not handle missing inner EncryptedContent
+ correctly. An attacker can craft malformed ASN.1-encoded PKCS#7 blobs
+ with missing content and trigger a NULL pointer dereference on parsing.
+
+ Applications that decrypt PKCS#7 data or otherwise parse PKCS#7
+ structures from untrusted sources are affected. OpenSSL clients and
+ servers are not affected.
+
+ This issue was reported to OpenSSL by Michal Zalewski (Google).
+ (CVE-2015-1790)
+ [Emilia Käsper]
+
+ *) CMS verify infinite loop with unknown hash function
+
+ When verifying a signedData message the CMS code can enter an infinite loop
+ if presented with an unknown hash function OID. This can be used to perform
+ denial of service against any system which verifies signedData messages using
+ the CMS code.
+ This issue was reported to OpenSSL by Johannes Bauer.
+ (CVE-2015-1792)
+ [Stephen Henson]
+
+ *) Race condition handling NewSessionTicket
+
+ If a NewSessionTicket is received by a multi-threaded client when attempting to
+ reuse a previous ticket then a race condition can occur potentially leading to
+ a double free of the ticket data.
+ (CVE-2015-1791)
+ [Matt Caswell]
+
+ *) Reject DH handshakes with parameters shorter than 768 bits.
+ [Kurt Roeckx and Emilia Kasper]
+
+ *) dhparam: generate 2048-bit parameters by default.
+ [Kurt Roeckx and Emilia Kasper]
+
+ Changes between 1.0.1l and 1.0.1m [19 Mar 2015]
+
+ *) Segmentation fault in ASN1_TYPE_cmp fix
+
+ The function ASN1_TYPE_cmp will crash with an invalid read if an attempt is
+ made to compare ASN.1 boolean types. Since ASN1_TYPE_cmp is used to check
+ certificate signature algorithm consistency this can be used to crash any
+ certificate verification operation and exploited in a DoS attack. Any
+ application which performs certificate verification is vulnerable including
+ OpenSSL clients and servers which enable client authentication.
+ (CVE-2015-0286)
+ [Stephen Henson]
+
+ *) ASN.1 structure reuse memory corruption fix
+
+ Reusing a structure in ASN.1 parsing may allow an attacker to cause
+ memory corruption via an invalid write. Such reuse is and has been
+ strongly discouraged and is believed to be rare.
+
+ Applications that parse structures containing CHOICE or ANY DEFINED BY
+ components may be affected. Certificate parsing (d2i_X509 and related
+ functions) are however not affected. OpenSSL clients and servers are
+ not affected.
+ (CVE-2015-0287)
+ [Stephen Henson]
+
+ *) PKCS7 NULL pointer dereferences fix
+
+ The PKCS#7 parsing code does not handle missing outer ContentInfo
+ correctly. An attacker can craft malformed ASN.1-encoded PKCS#7 blobs with
+ missing content and trigger a NULL pointer dereference on parsing.
+
+ Applications that verify PKCS#7 signatures, decrypt PKCS#7 data or
+ otherwise parse PKCS#7 structures from untrusted sources are
+ affected. OpenSSL clients and servers are not affected.
+
+ This issue was reported to OpenSSL by Michal Zalewski (Google).
+ (CVE-2015-0289)
+ [Emilia Käsper]
+
+ *) DoS via reachable assert in SSLv2 servers fix
+
+ A malicious client can trigger an OPENSSL_assert (i.e., an abort) in
+ servers that both support SSLv2 and enable export cipher suites by sending
+ a specially crafted SSLv2 CLIENT-MASTER-KEY message.
+
+ This issue was discovered by Sean Burford (Google) and Emilia Käsper
+ (OpenSSL development team).
+ (CVE-2015-0293)
+ [Emilia Käsper]
+
+ *) Use After Free following d2i_ECPrivatekey error fix
+
+ A malformed EC private key file consumed via the d2i_ECPrivateKey function
+ could cause a use after free condition. This, in turn, could cause a double
+ free in several private key parsing functions (such as d2i_PrivateKey
+ or EVP_PKCS82PKEY) and could lead to a DoS attack or memory corruption
+ for applications that receive EC private keys from untrusted
+ sources. This scenario is considered rare.
+
+ This issue was discovered by the BoringSSL project and fixed in their
+ commit 517073cd4b.
+ (CVE-2015-0209)
+ [Matt Caswell]
+
+ *) X509_to_X509_REQ NULL pointer deref fix
+
+ The function X509_to_X509_REQ will crash with a NULL pointer dereference if
+ the certificate key is invalid. This function is rarely used in practice.
+
+ This issue was discovered by Brian Carpenter.
+ (CVE-2015-0288)
+ [Stephen Henson]
+
+ *) Removed the export ciphers from the DEFAULT ciphers
+ [Kurt Roeckx]
+
+ Changes between 1.0.1k and 1.0.1l [15 Jan 2015]
+
+ *) Build fixes for the Windows and OpenVMS platforms
+ [Matt Caswell and Richard Levitte]
+
+ Changes between 1.0.1j and 1.0.1k [8 Jan 2015]
+
+ *) Fix DTLS segmentation fault in dtls1_get_record. A carefully crafted DTLS
+ message can cause a segmentation fault in OpenSSL due to a NULL pointer
+ dereference. This could lead to a Denial Of Service attack. Thanks to
+ Markus Stenberg of Cisco Systems, Inc. for reporting this issue.
+ (CVE-2014-3571)
+ [Steve Henson]
+
+ *) Fix DTLS memory leak in dtls1_buffer_record. A memory leak can occur in the
+ dtls1_buffer_record function under certain conditions. In particular this
+ could occur if an attacker sent repeated DTLS records with the same
+ sequence number but for the next epoch. The memory leak could be exploited
+ by an attacker in a Denial of Service attack through memory exhaustion.
+ Thanks to Chris Mueller for reporting this issue.
+ (CVE-2015-0206)
+ [Matt Caswell]
+
+ *) Fix issue where no-ssl3 configuration sets method to NULL. When openssl is
+ built with the no-ssl3 option and a SSL v3 ClientHello is received the ssl
+ method would be set to NULL which could later result in a NULL pointer
+ dereference. Thanks to Frank Schmirler for reporting this issue.
+ (CVE-2014-3569)
+ [Kurt Roeckx]
+
+ *) Abort handshake if server key exchange message is omitted for ephemeral
+ ECDH ciphersuites.
+
+ Thanks to Karthikeyan Bhargavan of the PROSECCO team at INRIA for
+ reporting this issue.
+ (CVE-2014-3572)
+ [Steve Henson]
+
+ *) Remove non-export ephemeral RSA code on client and server. This code
+ violated the TLS standard by allowing the use of temporary RSA keys in
+ non-export ciphersuites and could be used by a server to effectively
+ downgrade the RSA key length used to a value smaller than the server
+ certificate. Thanks for Karthikeyan Bhargavan of the PROSECCO team at
+ INRIA or reporting this issue.
+ (CVE-2015-0204)
+ [Steve Henson]
+
+ *) Fixed issue where DH client certificates are accepted without verification.
+ An OpenSSL server will accept a DH certificate for client authentication
+ without the certificate verify message. This effectively allows a client to
+ authenticate without the use of a private key. This only affects servers
+ which trust a client certificate authority which issues certificates
+ containing DH keys: these are extremely rare and hardly ever encountered.
+ Thanks for Karthikeyan Bhargavan of the PROSECCO team at INRIA or reporting
+ this issue.
+ (CVE-2015-0205)
+ [Steve Henson]
+
+ *) Ensure that the session ID context of an SSL is updated when its
+ SSL_CTX is updated via SSL_set_SSL_CTX.
+
+ The session ID context is typically set from the parent SSL_CTX,
+ and can vary with the CTX.
+ [Adam Langley]
+
+ *) Fix various certificate fingerprint issues.
+
+ By using non-DER or invalid encodings outside the signed portion of a
+ certificate the fingerprint can be changed without breaking the signature.
+ Although no details of the signed portion of the certificate can be changed
+ this can cause problems with some applications: e.g. those using the
+ certificate fingerprint for blacklists.
+
+ 1. Reject signatures with non zero unused bits.
+
+ If the BIT STRING containing the signature has non zero unused bits reject
+ the signature. All current signature algorithms require zero unused bits.
+
+ 2. Check certificate algorithm consistency.
+
+ Check the AlgorithmIdentifier inside TBS matches the one in the
+ certificate signature. NB: this will result in signature failure
+ errors for some broken certificates.
+
+ Thanks to Konrad Kraszewski from Google for reporting this issue.
+
+ 3. Check DSA/ECDSA signatures use DER.
+
+ Reencode DSA/ECDSA signatures and compare with the original received
+ signature. Return an error if there is a mismatch.
+
+ This will reject various cases including garbage after signature
+ (thanks to Antti Karjalainen and Tuomo Untinen from the Codenomicon CROSS
+ program for discovering this case) and use of BER or invalid ASN.1 INTEGERs
+ (negative or with leading zeroes).
+
+ Further analysis was conducted and fixes were developed by Stephen Henson
+ of the OpenSSL core team.
+
+ (CVE-2014-8275)
+ [Steve Henson]
+
+ *) Correct Bignum squaring. Bignum squaring (BN_sqr) may produce incorrect
+ results on some platforms, including x86_64. This bug occurs at random
+ with a very low probability, and is not known to be exploitable in any
+ way, though its exact impact is difficult to determine. Thanks to Pieter
+ Wuille (Blockstream) who reported this issue and also suggested an initial
+ fix. Further analysis was conducted by the OpenSSL development team and
+ Adam Langley of Google. The final fix was developed by Andy Polyakov of
+ the OpenSSL core team.
+ (CVE-2014-3570)
+ [Andy Polyakov]
+
+ *) Do not resume sessions on the server if the negotiated protocol
+ version does not match the session's version. Resuming with a different
+ version, while not strictly forbidden by the RFC, is of questionable
+ sanity and breaks all known clients.
+ [David Benjamin, Emilia Käsper]
+
+ *) Tighten handling of the ChangeCipherSpec (CCS) message: reject
+ early CCS messages during renegotiation. (Note that because
+ renegotiation is encrypted, this early CCS was not exploitable.)
+ [Emilia Käsper]
+
+ *) Tighten client-side session ticket handling during renegotiation:
+ ensure that the client only accepts a session ticket if the server sends
+ the extension anew in the ServerHello. Previously, a TLS client would
+ reuse the old extension state and thus accept a session ticket if one was
+ announced in the initial ServerHello.
+
+ Similarly, ensure that the client requires a session ticket if one
+ was advertised in the ServerHello. Previously, a TLS client would
+ ignore a missing NewSessionTicket message.
+ [Emilia Käsper]
+
+ Changes between 1.0.1i and 1.0.1j [15 Oct 2014]
+
+ *) SRTP Memory Leak.
+
+ A flaw in the DTLS SRTP extension parsing code allows an attacker, who
+ sends a carefully crafted handshake message, to cause OpenSSL to fail
+ to free up to 64k of memory causing a memory leak. This could be
+ exploited in a Denial Of Service attack. This issue affects OpenSSL
+ 1.0.1 server implementations for both SSL/TLS and DTLS regardless of
+ whether SRTP is used or configured. Implementations of OpenSSL that
+ have been compiled with OPENSSL_NO_SRTP defined are not affected.
+
+ The fix was developed by the OpenSSL team.
+ (CVE-2014-3513)
+ [OpenSSL team]
+
+ *) Session Ticket Memory Leak.
+
+ When an OpenSSL SSL/TLS/DTLS server receives a session ticket the
+ integrity of that ticket is first verified. In the event of a session
+ ticket integrity check failing, OpenSSL will fail to free memory
+ causing a memory leak. By sending a large number of invalid session
+ tickets an attacker could exploit this issue in a Denial Of Service
+ attack.
+ (CVE-2014-3567)
+ [Steve Henson]
+
+ *) Build option no-ssl3 is incomplete.
+
+ When OpenSSL is configured with "no-ssl3" as a build option, servers
+ could accept and complete a SSL 3.0 handshake, and clients could be
+ configured to send them.
+ (CVE-2014-3568)
+ [Akamai and the OpenSSL team]
+
+ *) Add support for TLS_FALLBACK_SCSV.
+ Client applications doing fallback retries should call
+ SSL_set_mode(s, SSL_MODE_SEND_FALLBACK_SCSV).
+ (CVE-2014-3566)
+ [Adam Langley, Bodo Moeller]
+
+ *) Add additional DigestInfo checks.
+
+ Reencode DigestInto in DER and check against the original when
+ verifying RSA signature: this will reject any improperly encoded
+ DigestInfo structures.
+
+ Note: this is a precautionary measure and no attacks are currently known.
+
+ [Steve Henson]
+
+ Changes between 1.0.1h and 1.0.1i [6 Aug 2014]
+
+ *) Fix SRP buffer overrun vulnerability. Invalid parameters passed to the
+ SRP code can be overrun an internal buffer. Add sanity check that
+ g, A, B < N to SRP code.
+
+ Thanks to Sean Devlin and Watson Ladd of Cryptography Services, NCC
+ Group for discovering this issue.
+ (CVE-2014-3512)
+ [Steve Henson]
+
+ *) A flaw in the OpenSSL SSL/TLS server code causes the server to negotiate
+ TLS 1.0 instead of higher protocol versions when the ClientHello message
+ is badly fragmented. This allows a man-in-the-middle attacker to force a
+ downgrade to TLS 1.0 even if both the server and the client support a
+ higher protocol version, by modifying the client's TLS records.
+
+ Thanks to David Benjamin and Adam Langley (Google) for discovering and
+ researching this issue.
+ (CVE-2014-3511)
+ [David Benjamin]
+
+ *) OpenSSL DTLS clients enabling anonymous (EC)DH ciphersuites are subject
+ to a denial of service attack. A malicious server can crash the client
+ with a null pointer dereference (read) by specifying an anonymous (EC)DH
+ ciphersuite and sending carefully crafted handshake messages.
+
+ Thanks to Felix Gröbert (Google) for discovering and researching this
+ issue.
+ (CVE-2014-3510)
+ [Emilia Käsper]
+
+ *) By sending carefully crafted DTLS packets an attacker could cause openssl
+ to leak memory. This can be exploited through a Denial of Service attack.
+ Thanks to Adam Langley for discovering and researching this issue.
+ (CVE-2014-3507)
+ [Adam Langley]
+
+ *) An attacker can force openssl to consume large amounts of memory whilst
+ processing DTLS handshake messages. This can be exploited through a
+ Denial of Service attack.
+ Thanks to Adam Langley for discovering and researching this issue.
+ (CVE-2014-3506)
+ [Adam Langley]
+
+ *) An attacker can force an error condition which causes openssl to crash
+ whilst processing DTLS packets due to memory being freed twice. This
+ can be exploited through a Denial of Service attack.
+ Thanks to Adam Langley and Wan-Teh Chang for discovering and researching
+ this issue.
+ (CVE-2014-3505)
+ [Adam Langley]
+
+ *) If a multithreaded client connects to a malicious server using a resumed
+ session and the server sends an ec point format extension it could write
+ up to 255 bytes to freed memory.
+
+ Thanks to Gabor Tyukasz (LogMeIn Inc) for discovering and researching this
+ issue.
+ (CVE-2014-3509)
+ [Gabor Tyukasz]
+
+ *) A malicious server can crash an OpenSSL client with a null pointer
+ dereference (read) by specifying an SRP ciphersuite even though it was not
+ properly negotiated with the client. This can be exploited through a
+ Denial of Service attack.
+
+ Thanks to Joonas Kuorilehto and Riku Hietamäki (Codenomicon) for
+ discovering and researching this issue.
+ (CVE-2014-5139)
+ [Steve Henson]
+
+ *) A flaw in OBJ_obj2txt may cause pretty printing functions such as
+ X509_name_oneline, X509_name_print_ex et al. to leak some information
+ from the stack. Applications may be affected if they echo pretty printing
+ output to the attacker.
+
+ Thanks to Ivan Fratric (Google) for discovering this issue.
+ (CVE-2014-3508)
+ [Emilia Käsper, and Steve Henson]
+
+ *) Fix ec_GFp_simple_points_make_affine (thus, EC_POINTs_mul etc.)
+ for corner cases. (Certain input points at infinity could lead to
+ bogus results, with non-infinity inputs mapped to infinity too.)
+ [Bodo Moeller]
+
+ Changes between 1.0.1g and 1.0.1h [5 Jun 2014]
+
+ *) Fix for SSL/TLS MITM flaw. An attacker using a carefully crafted
+ handshake can force the use of weak keying material in OpenSSL
+ SSL/TLS clients and servers.
+
+ Thanks to KIKUCHI Masashi (Lepidum Co. Ltd.) for discovering and
+ researching this issue. (CVE-2014-0224)
+ [KIKUCHI Masashi, Steve Henson]
+
+ *) Fix DTLS recursion flaw. By sending an invalid DTLS handshake to an
+ OpenSSL DTLS client the code can be made to recurse eventually crashing
+ in a DoS attack.
+
+ Thanks to Imre Rad (Search-Lab Ltd.) for discovering this issue.
+ (CVE-2014-0221)
+ [Imre Rad, Steve Henson]
+
+ *) Fix DTLS invalid fragment vulnerability. A buffer overrun attack can
+ be triggered by sending invalid DTLS fragments to an OpenSSL DTLS
+ client or server. This is potentially exploitable to run arbitrary
+ code on a vulnerable client or server.
+
+ Thanks to Jüri Aedla for reporting this issue. (CVE-2014-0195)
+ [Jüri Aedla, Steve Henson]
+
+ *) Fix bug in TLS code where clients enable anonymous ECDH ciphersuites
+ are subject to a denial of service attack.
+
+ Thanks to Felix Gröbert and Ivan Fratric at Google for discovering
+ this issue. (CVE-2014-3470)
+ [Felix Gröbert, Ivan Fratric, Steve Henson]
+
+ *) Harmonize version and its documentation. -f flag is used to display
+ compilation flags.
+ [mancha <mancha1@zoho.com>]
+
+ *) Fix eckey_priv_encode so it immediately returns an error upon a failure
+ in i2d_ECPrivateKey.
+ [mancha <mancha1@zoho.com>]
+
+ *) Fix some double frees. These are not thought to be exploitable.
+ [mancha <mancha1@zoho.com>]
+
+ Changes between 1.0.1f and 1.0.1g [7 Apr 2014]
+
+ *) A missing bounds check in the handling of the TLS heartbeat extension
+ can be used to reveal up to 64k of memory to a connected client or
+ server.
+
+ Thanks for Neel Mehta of Google Security for discovering this bug and to
+ Adam Langley <agl@chromium.org> and Bodo Moeller <bmoeller@acm.org> for
+ preparing the fix (CVE-2014-0160)
+ [Adam Langley, Bodo Moeller]
+
+ *) Fix for the attack described in the paper "Recovering OpenSSL
+ ECDSA Nonces Using the FLUSH+RELOAD Cache Side-channel Attack"
+ by Yuval Yarom and Naomi Benger. Details can be obtained from:
+ http://eprint.iacr.org/2014/140
+
+ Thanks to Yuval Yarom and Naomi Benger for discovering this
+ flaw and to Yuval Yarom for supplying a fix (CVE-2014-0076)
+ [Yuval Yarom and Naomi Benger]
+
+ *) TLS pad extension: draft-agl-tls-padding-03
+
+ Workaround for the "TLS hang bug" (see FAQ and PR#2771): if the
+ TLS client Hello record length value would otherwise be > 255 and
+ less that 512 pad with a dummy extension containing zeroes so it
+ is at least 512 bytes long.
+
+ [Adam Langley, Steve Henson]
+
+ Changes between 1.0.1e and 1.0.1f [6 Jan 2014]
+
+ *) Fix for TLS record tampering bug. A carefully crafted invalid
+ handshake could crash OpenSSL with a NULL pointer exception.
+ Thanks to Anton Johansson for reporting this issues.
+ (CVE-2013-4353)
+
+ *) Keep original DTLS digest and encryption contexts in retransmission
+ structures so we can use the previous session parameters if they need
+ to be resent. (CVE-2013-6450)
+ [Steve Henson]
+
+ *) Add option SSL_OP_SAFARI_ECDHE_ECDSA_BUG (part of SSL_OP_ALL) which
+ avoids preferring ECDHE-ECDSA ciphers when the client appears to be
+ Safari on OS X. Safari on OS X 10.8..10.8.3 advertises support for
+ several ECDHE-ECDSA ciphers, but fails to negotiate them. The bug
+ is fixed in OS X 10.8.4, but Apple have ruled out both hot fixing
+ 10.8..10.8.3 and forcing users to upgrade to 10.8.4 or newer.
+ [Rob Stradling, Adam Langley]
+
+ Changes between 1.0.1d and 1.0.1e [11 Feb 2013]
+
+ *) Correct fix for CVE-2013-0169. The original didn't work on AES-NI
+ supporting platforms or when small records were transferred.
+ [Andy Polyakov, Steve Henson]
+
+ Changes between 1.0.1c and 1.0.1d [5 Feb 2013]
+
+ *) Make the decoding of SSLv3, TLS and DTLS CBC records constant time.
+
+ This addresses the flaw in CBC record processing discovered by
+ Nadhem Alfardan and Kenny Paterson. Details of this attack can be found
+ at: http://www.isg.rhul.ac.uk/tls/
+
+ Thanks go to Nadhem Alfardan and Kenny Paterson of the Information

+ (CVE-2013-0169)
+ [Emilia Käsper, Adam Langley, Ben Laurie, Andy Polyakov, Steve Henson]
+
+ *) Fix flaw in AESNI handling of TLS 1.2 and 1.1 records for CBC mode

+
+ *) Make openssl verify return errors.
+ [Chris Palmer <palmer@google.com> and Ben Laurie]
+
+ *) Call OCSP Stapling callback after ciphersuite has been chosen, so
+ the right response is stapled. Also change SSL_get_certificate()
+ so it returns the certificate actually sent.
+ See http://rt.openssl.org/Ticket/Display.html?id=2836.
+ [Rob Stradling <rob.stradling@comodo.com>]
+

+ *) OpenSSL 1.0.0 sets SSL_OP_ALL to 0x80000FFFL and OpenSSL 1.0.1 and
+ 1.0.1a set SSL_OP_NO_TLSv1_1 to 0x00000400L which would unfortunately
+ mean any application compiled against OpenSSL 1.0.0 headers setting
+ SSL_OP_ALL would also set SSL_OP_NO_TLSv1_1, unintentionally disablng
+ TLS 1.1 also. Fix this by changing the value of SSL_OP_NO_TLSv1_1 to
+ 0x10000000L Any application which was previously compiled against
+ OpenSSL 1.0.1 or 1.0.1a headers and which cares about SSL_OP_NO_TLSv1_1
+ will need to be recompiled as a result. Letting be results in
+ inability to disable specifically TLS 1.1 and in client context,
+ in unlike event, limit maximum offered version to TLS 1.0 [see below].
+ [Steve Henson]
+
+ *) In order to ensure interoperabilty SSL_OP_NO_protocolX does not
+ disable just protocol X, but all protocols above X *if* there are
+ protocols *below* X still enabled. In more practical terms it means
+ that if application wants to disable TLS1.0 in favor of TLS1.1 and
+ above, it's not sufficient to pass SSL_OP_NO_TLSv1, one has to pass
+ SSL_OP_NO_TLSv1|SSL_OP_NO_SSLv3|SSL_OP_NO_SSLv2. This applies to
+ client side.

+ Changes between 1.0.1 and 1.0.1a [19 Apr 2012]

- Changes between 0.9.8r and 0.9.8s [4 Jan 2012]
-
- *) Nadhem Alfardan and Kenny Paterson have discovered an extension
- of the Vaudenay padding oracle attack on CBC mode encryption
- which enables an efficient plaintext recovery attack against
- the OpenSSL implementation of DTLS. Their attack exploits timing
- differences arising during decryption processing. A research
- paper describing this attack can be found at:
- http://www.isg.rhul.ac.uk/~kp/dtls.pdf
- Thanks go to Nadhem Alfardan and Kenny Paterson of the Information
- Security Group at Royal Holloway, University of London
- (www.isg.rhul.ac.uk) for discovering this flaw and to Robin Seggelmann

- [Adam Langley (Google)]
-
- *) Fix handling of BN_BLINDING: now BN_BLINDING_invert_ex (rather than
- BN_BLINDING_invert_ex) calls BN_BLINDING_update, ensuring that concurrent
- threads won't reuse the same blinding coefficients.
-
- This also avoids the need to obtain the CRYPTO_LOCK_RSA_BLINDING
