A flaw in the OpenSSL SSL/TLS server code where an old bug workaround allows malicious clients to modify the stored session cache ciphersuite. In some cases the ciphersuite can be downgraded to a weaker one on subsequent connections. This issue only affects OpenSSL based SSL/TLS server if it uses OpenSSL's internal caching mechanisms and the SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG flag (many applications enable this by using the SSL_OP_ALL option).
