Details

It was discovered that libvorbis did not correctly handle certain malformed
ogg files. If a user were tricked into opening a specially 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.
