Details

It was discovered that libvorbis did not correctly handle ogg files with
underpopulated Huffman trees. 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. (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.
