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.
