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
-------------------------------------------------------------------
1 media-libs/libtheora < 1.1.1 >= 1.1.1

Description
===========
An integer overflow flaw has been discovered in libtheora.

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:
