Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-201206-18
(GnuTLS: Multiple vulnerabilities)

Multiple vulnerabilities have been found in GnuTLS:
An error in libgnutls does not properly sanitize '\\0' characters from
certificate fields (CVE-2009-2730).
An error in the TLS and SSL protocols mistreats renegotiation
handshakes (CVE-2009-3555).
A boundary error in the 'gnutls_session_get_data()' function in
gnutls_session.c could cause a buffer overflow (CVE-2011-4128).
An error in the '_gnutls_ciphertext2compressed()' function in
gnutls_cipher.c could cause memory corruption (CVE-2012-1573).

Impact :

arbitrary SSL servers or cause a Denial of Service condition in
applications linked against GnuTLS.

Workaround :

There is no known workaround at this time.
