crafted ogg file with an application that uses libvorbis, an attacker
could execute arbitrary code with the user's privileges.
(CVE-2009-2663)

USN-682-1 provided updated libvorbis packages to fix multiple security
vulnerabilities. The upstream security patch to fix CVE-2008-1420
introduced a regression when reading sound files encoded with
libvorbis 1.0beta1. This update corrects the problem.

It was discovered that libvorbis did not correctly handle certain
malformed sound files. If a user were tricked into opening a specially
crafted sound file with an application that uses libvorbis, an
attacker could execute arbitrary code with the user's privileges.
(CVE-2008-1420).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
