Synopsis
========

An integer overflow in libtheora might allow remote attackers to
execute arbitrary code or cause a Denial of Service condition.

Background
==========

libtheora is the reference implementation of Theora, a free and open
video compression format from the Xiph.org Foundation.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected

Impact
======

A remote attacker could execute arbitrary code or cause a Denial of
Service condition.

Workaround

There is no known workaround at this time.

Resolution
==========

All libtheora users should upgrade to the latest version:
