Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

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

Workaround :

If possible, disable the use of SSL 2.0 in all OpenSSL-enabled
