+OpenSSL Security Advisory [02 Nov 2017]
+========================================
+
+bn_sqrx8x_internal carry bug on x86_64 (CVE-2017-3736)
+======================================================
+
+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.
+
+This only affects processors that support the BMI1, BMI2 and ADX extensions
like
+Intel Broadwell (5th generation) and later or AMD Ryzen.
+
+Note: This issue is very similar to CVE-2017-3732 and CVE-2015-3193 but must be
+treated as a separate problem.
+
+OpenSSL 1.1.0 users should upgrade to 1.1.0g
+OpenSSL 1.0.2 users should upgrade to 1.0.2m
+
+This issue was reported to OpenSSL on 10th August 2017 by the OSS-Fuzz project.
+The fix was developed by Andy Polyakov of the OpenSSL development team.
+
+Malformed X.509 IPAddressFamily could cause OOB read (CVE-2017-3735)
+====================================================================
+
+Severity: Low
+
+This issue was previously announced in security advisory
+https://www.openssl.org/news/secadv/20170828.txt, but the fix has not
previously
+been included in a release due to its low severity.
+
+OpenSSL 1.1.0 users should upgrade to 1.1.0g
+OpenSSL 1.0.2 users should upgrade to 1.0.2m
+
+
+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.
