- Changes between 1.1.0h and 1.1.0i [xx XXX xxxx]
+ Changes between 1.1.0j and 1.1.0k [xx XXX xxxx]
- *)
+ *) Added SCA hardening for modular field inversion in EC_GROUP through
+ a new dedicated field_inv() pointer in EC_METHOD.
+ This also addresses a leakage affecting conversions from projective
+ to affine coordinates.
+ [Billy Bob Brumley, Nicola Tuveri]
+
+ *) Fix a use after free bug in d2i_X509_PUBKEY when overwriting a
+ re-used X509_PUBKEY object if the second PUBKEY is malformed.
+ [Bernd Edlinger]
+
+ *) Move strictness check from EVP_PKEY_asn1_new() to EVP_PKEY_asn1_add0().
+ [Richard Levitte]
+
+ *) Remove the 'dist' target and add a tarball building script. The
+ 'dist' target has fallen out of use, and it shouldn't be
+ necessary to configure just to create a source distribution.
+ [Richard Levitte]
+
+ Changes between 1.1.0i and 1.1.0j [20 Nov 2018]
+
+ *) Timing vulnerability in DSA signature generation
+
+ The OpenSSL DSA signature algorithm has been shown to be vulnerable to a
+ timing side channel attack. An attacker could use variations in the signing
+ algorithm to recover the private key.
+
+ This issue was reported to OpenSSL on 16th October 2018 by Samuel Weiser.
+ (CVE-2018-0734)
+ [Paul Dale]
+
+ *) Timing vulnerability in ECDSA signature generation
+
+ The OpenSSL ECDSA signature algorithm has been shown to be vulnerable to a
+ timing side channel attack. An attacker could use variations in the signing
+ algorithm to recover the private key.
+
+ This issue was reported to OpenSSL on 25th October 2018 by Samuel Weiser.
+ (CVE-2018-0735)
+ [Paul Dale]
+
+ *) Add coordinate blinding for EC_POINT and implement projective
+ coordinate blinding for generic prime curves as a countermeasure to
+ chosen point SCA attacks.
+ [Sohaib ul Hassan, Nicola Tuveri, Billy Bob Brumley]
+
+ Changes between 1.1.0h and 1.1.0i [14 Aug 2018]
+
+ *) Client DoS due to large DH parameter
+
+ During key agreement in a TLS handshake using a DH(E) based ciphersuite a
+ malicious server can send a very large prime value to the client. This will
+ cause the client to spend an unreasonably long period of time generating a
+ key for this prime resulting in a hang until the client has finished. This
+ could be exploited in a Denial Of Service attack.
+
+ This issue was reported to OpenSSL on 5th June 2018 by Guido Vranken
+ (CVE-2018-0732)
+ [Guido Vranken]
+
+ *) Cache timing vulnerability in RSA Key Generation
+
+ The OpenSSL RSA Key generation algorithm has been shown to be vulnerable to
+ a cache timing side channel attack. An attacker with sufficient access to
+ mount cache timing attacks during the RSA key generation process could
+ recover the private key.
+
+ This issue was reported to OpenSSL on 4th April 2018 by Alejandro Cabrera
+ Aldaya, Billy Brumley, Cesar Pereida Garcia and Luis Manuel Alvarez Tapia.
+ (CVE-2018-0737)
+ [Billy Brumley]
+
+ *) Make EVP_PKEY_asn1_new() a bit stricter about its input. A NULL pem_str
+ parameter is no longer accepted, as it leads to a corrupt table. NULL
+ pem_str is reserved for alias entries only.
+ [Richard Levitte]
+
+ *) Revert blinding in ECDSA sign and instead make problematic addition
+ length-invariant. Switch even to fixed-length Montgomery multiplication.
+ [Andy Polyakov]
+
+ *) Change generating and checking of primes so that the error rate of not
+ being prime depends on the intended use based on the size of the input.
+ For larger primes this will result in more rounds of Miller-Rabin.
+ The maximal error rate for primes with more than 1080 bits is lowered
+ to 2^-128.
+ [Kurt Roeckx, Annie Yousar]
+
+ *) Increase the number of Miller-Rabin rounds for DSA key generating to 64.
+ [Kurt Roeckx]
+
+ *) Add blinding to ECDSA and DSA signatures to protect against side channel
+ attacks discovered by Keegan Ryan (NCC Group).
+ [Matt Caswell]
+
+ *) When unlocking a pass phrase protected PEM file or PKCS#8 container, we
+ now allow empty (zero character) pass phrases.
+ [Richard Levitte]
+
+ *) Certificate time validation (X509_cmp_time) enforces stricter
+ compliance with RFC 5280. Fractional seconds and timezone offsets
+ are no longer allowed.
+ [Emilia Käsper]
+
+ *) Fixed a text canonicalisation bug in CMS
+
+ Where a CMS detached signature is used with text content the text goes
+ through a canonicalisation process first prior to signing or verifying a
+ signature. This process strips trailing space at the end of lines, converts
+ line terminators to CRLF and removes additional trailing line terminators
+ at the end of a file. A bug in the canonicalisation process meant that
+ some characters, such as form-feed, were incorrectly treated as whitespace
+ and removed. This is contrary to the specification (RFC5485). This fix
+ could mean that detached text data signed with an earlier version of
+ OpenSSL 1.1.0 may fail to verify using the fixed version, or text data
+ signed with a fixed OpenSSL may fail to verify with an earlier version of
+ OpenSSL 1.1.0. A workaround is to only verify the canonicalised text data
+ and use the "-binary" flag (for the "cms" command line application) or set
+ the SMIME_BINARY/PKCS7_BINARY/CMS_BINARY flags (if using CMS_verify()).
+ [Matt Caswell]
