Description

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.

Solution(s)

  • http-openssl-1_0_1-upgrade-1_0_1_r
  • http-openssl-1_0_2-upgrade-1_0_2_f
