CVE-2015-3197
Last modified
CVE-2015-3197 is a vulnerability of currently unknown severity. ssl/s2_srvr.c in OpenSSL 1.0.1 before 1.0.1r and 1.0.2 before 1.0.2f does not prevent use of disabled ciphers, which makes it easier for man-in-the-middle attackers to defeat cryptographic protection mechanisms by performing computations on SSLv2 traffic, related to the get_client_master_key and get_client_hello functions.. EPSS estimates a 10.73% chance of exploitation in the next 30 days.
