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] + *) Montgomery multiplication may produce incorrect results There is a carry propagating bug in the Broadwell-specific Montgomery |
