It also means that maintaining + the OPENSSL_NO_TLSEXT option within the code is very invasive (and probably + not well tested). Therefore the OPENSSL_NO_TLSEXT option has been removed. + [Matt Caswell] + + *) Removed support for the two export grade static DH ciphersuites + EXP-DH-RSA-DES-CBC-SHA and EXP-DH-DSS-DES-CBC-SHA. These two ciphersuites + were newly added (along with a number of other static DH ciphersuites) to + 1.0.2. However the two export ones have *never* worked since they were + introduced. It seems strange in any case to be adding new export + ciphersuites, and given "logjam" it also does not seem correct to fix them. + [Matt Caswell] + + *) Version negotiation has been rewritten. In particular SSLv23_method(), + SSLv23_client_method() and SSLv23_server_method() have been deprecated, + and turned into macros which simply call the new preferred function names + TLS_method(), TLS_client_method() and TLS_server_method().

Users should not attempt to access internal structures + directly.

This + feature only applies on 64 bit x86 architecture platforms that support AES + NI instructions. A defect in the implementation of "multiblock" can cause + OpenSSL's internal write buffer to become incorrectly set to NULL when + using non-blocking IO. Typically, when the user application is using a + socket BIO for writing, this will only result in a failed connection. + However if some other BIO is used then it is likely that a segmentation + fault will be triggered, thus enabling a potential DoS attack. + + This issue was reported to OpenSSL by Daniel Danner and Rainer Mueller. + (CVE-2015-0290) + [Matt Caswell] + + *) Segmentation fault in DTLSv1_listen fix + + The DTLSv1_listen function is intended to be stateless and processes the + initial ClientHello from many peers. It is common for user code to loop + over the call to DTLSv1_listen until a valid ClientHello is received with + an associated cookie. A defect in the implementation of DTLSv1_listen means + that state is preserved in the SSL object from one invocation to the next + that can lead to a segmentation fault. Errors processing the initial + ClientHello can trigger this scenario. An example of such an error could be + that a DTLS1.0 only client is attempting to connect to a DTLS1.2 only + server. + + This issue was reported to OpenSSL by Per Allansson. + (CVE-2015-0207) + [Matt Caswell] + + *) 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] + + *) Segmentation fault for invalid PSS parameters fix + + The signature verification routines will crash with a NULL pointer + dereference if presented with an ASN.1 signature using the RSA PSS + algorithm and invalid parameters. 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 was reported to OpenSSL by Brian Carpenter. + (CVE-2015-0208) + [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] + + *) Empty CKE with client auth and DHE fix + + If client auth is used then a server can seg fault in the event of a DHE + ciphersuite being selected and a zero length ClientKeyExchange message + being sent by the client. This could be exploited in a DoS attack. + (CVE-2015-1787) + [Matt Caswell] + + *) Handshake with unseeded PRNG fix + + Under certain conditions an OpenSSL 1.0.2 client can complete a handshake + with an unseeded PRNG. The conditions are: + - The client is on a platform where the PRNG has not been seeded + automatically, and the user has not seeded manually + - A protocol specific client method version has been used (i.e. not + SSL_client_methodv23) + - A ciphersuite is used that does not require additional random data from + the PRNG beyond the initial ClientHello client random (e.g. PSK-RC4-SHA). + + If the handshake succeeds then the client random that has been used will + have been generated from a PRNG with insufficient entropy and therefore the + output may be predictable. + + For example using the following command with an unseeded openssl will + succeed on an unpatched platform: + + openssl s_client -psk 1a2b3c4d -tls1_2 -cipher PSK-RC4-SHA + (CVE-2015-0285) + [Matt Caswell] + + *) 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.
