SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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).
A remote attacker could perform man-in-the-middle attacks to spoof arbitrary SSL servers or cause a Denial of Service condition in applications linked against GnuTLS.
There is no known workaround at this time.
SolutionAll GnuTLS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-libs/gnutls-2.12.18'
