This script is Copyright (C) 2008-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200806-09
(libvorbis: Multiple vulnerabilities)

Will Drewry of the Google Security Team reported multiple
vulnerabilities in libvorbis:
A zero value for 'codebook.dim' is not properly handled, leading to a
crash, infinite loop or triggering an integer overflow
An integer overflow in 'residue partition value' evaluation might lead
to a heap-based buffer overflow (CVE-2008-1420).
An integer overflow in a certain 'quantvals' and 'quantlist'
calculation might lead to a heap-based buffer overflow

Impact :

A remote attacker could exploit these vulnerabilities by enticing a
user to open a specially crafted Ogg Vorbis file or network stream with
an application using libvorbis. This might lead to the execution of
arbitrary code with the privileges of the user playing the file or a
Denial of Service by a crash or CPU consumption.

Workaround :

There is no known workaround at this time.
