*) Support for SSL_OP_NO_ENCRYPT_THEN_MAC in SSL_CONF_cmd.
[Emilia Käsper]
- Changes between 1.1.0b and 1.1.0c [xx XXX xxxx]
+ Changes between 1.1.0c and 1.1.0d [26 Jan 2017]
+
+ *) Truncated packet could crash via OOB read
+
+ If one side of an SSL/TLS path is running on a 32-bit host and a specific
+ cipher is being used, then a truncated packet can cause that host to
+ perform an out-of-bounds read, usually resulting in a crash.
+
+ This issue was reported to OpenSSL by Robert Święcki of Google.
+ (CVE-2017-3731)
+ [Andy Polyakov]
+
+ *) Bad (EC)DHE parameters cause a client crash
+
+ If a malicious server supplies bad parameters for a DHE or ECDHE key
+ exchange then this can result in the client attempting to dereference a
+ NULL pointer leading to a client crash. This could be exploited in a Denial
+ of Service attack.
+
+ This issue was reported to OpenSSL by Guido Vranken.
+ (CVE-2017-3730)
+ [Matt Caswell]
+
+ *) BN_mod_exp may produce incorrect results on x86_64
+
+ There is a carry propagating bug in the x86_64 Montgomery squaring
+ procedure. No EC algorithms are affected. Analysis suggests that attacks
+ against RSA and DSA as a result of this defect would be very difficult to
+ perform and are not believed likely. Attacks against DH are considered just
+ feasible (although very difficult) because most of the work necessary to
+ deduce information about a private key may be performed offline. The amount
+ of resources required for such an attack would be very significant and
+ likely only accessible to a limited number of attackers. An attacker would
+ additionally need online access to an unpatched system using the target
+ private key in a scenario with persistent DH parameters and a private
+ key that is shared between multiple clients. For example this can occur by
+ default in OpenSSL DHE based SSL/TLS ciphersuites. Note: This issue is very
+ similar to CVE-2015-3193 but must be treated as a separate problem.
+
+ This issue was reported to OpenSSL by the OSS-Fuzz project.
+ (CVE-2017-3732)
+ [Andy Polyakov]
