Protocol Version Rollback Vulnerability in OpenSSL

CVE-2005-2969 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:P/A:N

The SSL/TLS server implementation in OpenSSL 0.9.7 before 0.9.7h and 0.9.8 before 0.9.8a, when using the SSL_OP_MSIE_SSLV2_RSA_PADDING option, disables a verification step that is required for preventing protocol version rollback attacks, which allows remote attackers to force a client and server to use a weaker protocol than needed via a man-in-the-middle attack.
