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	Architecture(s)
media-libs/libtheora	< 1.1.1	>= 1.1.1	All supported architectures

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:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=media-libs/libtheora-1.1.1"
