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. This issue was reported to OpenSSL by the OSS-Fuzz project. (CVE-2017-3736) [Andy Polyakov] *) Malformed X.509 IPAddressFamily could cause OOB read If an X.509 certificate has a malformed IPAddressFamily extension, OpenSSL could do a one-byte buffer overread. The most likely result would be an erroneous display of the certificate in text format. This issue was reported to OpenSSL by the OSS-Fuzz project. (CVE-2017-3735) [Rich Salz] *) Ignore the '-named_curve auto' value for compatibility of applications with OpenSSL 1.0.2.
