A vulnerability has been identified in various Cisco products, which could be exploited by attackers to bypass certain security restrictions. This issue is due to an error in the "SSL_OP_MSIE_SSLV2_RSA_PADDING" option of OpenSSL that does not properly reject SSL 2.0 sessions when a client supports SSL 3.0 or TLS 1.0, which could be exploited by malicious people to conduct MITM (Man in the Middle) attacks and force a client and a server to negotiate the SSL 2.0 protocol instead of SSL 3.0 or TLS 1.0. For additional information, see : FrSIRT/ADV-2005-2036
