This script is Copyright (C) 2008-2014 Tenable Network Security, Inc.


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-200806-08
(OpenSSL: Denial of Service)

Ossi Herrala and Jukka Taimisto of Codenomicon discovered two
vulnerabilities:
A double free() call in the TLS server name extension (CVE-2008-0891).
The OpenSSL client code does not properly handle servers that omit the
Server Key Exchange message in the TLS handshake (CVE-2008-1672).

Impact :

A remote attacker could connect to a vulnerable server, or entice a
daemon to connect to a malicious server, causing a Denial of Service of
the daemon in both cases.

Workaround :

There is no known workaround at this time.

All OpenSSL users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=dev-libs/openssl-0.9.8g-r2'

Risk factor :

Medium / CVSS Base Score : 4.3
