an attacker could cause a denial of service. (CVE-2008-2009)

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 cause a denial of service or possibly execute arbitrary code
with the user's privileges. (CVE-2009-3379).

has attempted to automatically clean and format it as much as possible
without introducing additional issues."
