Description

David Thiel discovered that libvorbis did not correctly verify the size of certain headers, and did not correctly clean up a broken stream. If a user were tricked into processing a specially crafted Vorbis stream, a remote attacker could execute arbitrary code with the user's privileges.

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.
