Bugzilla: 659462: CVE-2010-4180 openssl: NETSCAPE_REUSE_CIPHER_CHANGE_BUG ciphersuite downgrade attack
IAVA: 2012-B-0038

Details

The MITRE CVE dictionary describes this issue as:

OpenSSL before 0.9.8q, and 1.0.x before 1.0.0c, when SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is enabled, does not properly prevent modification of the ciphersuite in the session cache, which allows remote attackers to force the downgrade to an unintended cipher via vectors involving sniffing network traffic to discover a session identifier.
