[GLSA-200510-11] OpenSSL: SSL 2.0 protocol rollback |

OpenSSL: SSL 2.0 protocol rollback Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200510-11 (OpenSSL: SSL 2.0 protocol rollback) Applications setting the SSL_OP_MSIE_SSLV2_RSA_PADDING option (or the SSL_OP_ALL option, that implies it) can be forced by a third-party to fallback to the less secure SSL 2.0 protocol, even if both parties support the more secure SSL 3.0 or TLS 1.0 protocols. Impact A man-in-the-middle attacker can weaken the encryption used to communicate between two parties, potentially revealing sensitive information. Workaround If possible, disable the use of SSL 2.0 in all OpenSSL-enabled applications.
