+OpenSSL Security Advisory [26 Jan 2017]
+========================================
+
+Truncated packet could crash via OOB read (CVE-2017-3731)
+=========================================================
+
+Severity: Moderate
+
+If an SSL/TLS server or client is running on a 32-bit host, and a specific
+cipher is being used, then a truncated packet can cause that server or client
+to perform an out-of-bounds read, usually resulting in a crash.
+
+For OpenSSL 1.1.0, the crash can be triggered when using CHACHA20/POLY1305;
+users should upgrade to 1.1.0d
+
+For Openssl 1.0.2, the crash can be triggered when using RC4-MD5; users who
have
+not disabled that algorithm should update to 1.0.2k
+
+This issue was reported to OpenSSL on 13th November 2016 by Robert Święcki of
+Google. The fix was developed by Andy Polyakov of the OpenSSL development team.
+
+Bad (EC)DHE parameters cause a client crash (CVE-2017-3730)
+===========================================================
+
+Severity: Moderate
+
+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.
+
+OpenSSL 1.1.0 users should upgrade to 1.1.0d
+
+This issue does not affect OpenSSL version 1.0.2.
+
+Note that this issue was fixed prior to it being recognised as a security
+concern. This means the git commit with the fix does not contain the CVE
+identifier. The relevant fix commit can be identified by commit hash efbe126e3.
+
+This issue was reported to OpenSSL on 14th January 2017 by Guido Vranken. The
+fix was developed by Matt Caswell of the OpenSSL development team.
+
+BN_mod_exp may produce incorrect results on x86_64 (CVE-2017-3732)
+==================================================================
+
+Severity: Moderate
+
+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.
+
+OpenSSL 1.1.0 users should upgrade to 1.1.0d
+OpenSSL 1.0.2 users should upgrade to 1.0.2k
+
+This issue was reported to OpenSSL on 15th January 2017 by the OSS-Fuzz
project.
+The fix was developed by Andy Polyakov of the OpenSSL development team.
+
+Montgomery multiplication may produce incorrect results (CVE-2016-7055)
+=======================================================================
+
+Severity: Low
+
+This issue was previously fixed in 1.1.0c and covered in security advisory
+https://www.openssl.org/news/secadv/20161110.txt
+
+OpenSSL 1.0.2k users should upgrade to 1.0.2k
+
+
+Note
+====
+
+Support for version 1.0.1 ended on 31st December 2016. Support for versions
+0.9.8 and 1.0.0 ended on 31st December 2015. Those versions are no longer
+receiving security updates.
