Gentoo Linux Security Advisory

Title: libtheora: Arbitrary code execution (GLSA 201312-04)
Severity: normal
Exploitable: remote
Date: December 03, 2013
Bug(s): #298039
ID: 201312-04

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: media-libs/libtheora
Vulnerable: < 1.1.1
Unaffected: >= 1.1.1
Architectures: 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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=media-libs/libtheora-1.1.1"
   
Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these packages.
