=====================================================================

 

1. Summary:

 

Updated libvorbis packages that fix various security issues are now

available for Red Hat Enterprise Linux 2.1.

 

This update has been rated as having important security impact by the Red

Hat Security Response Team.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64

Red Hat Linux Advanced Workstation 2.1 - ia64

Red Hat Enterprise Linux ES version 2.1 - i386

Red Hat Enterprise Linux WS version 2.1 - i386

 

3. Description:

 

The libvorbis packages contain runtime libraries for use in programs that

support Ogg Vorbis. Ogg Vorbis is a fully open, non-proprietary, patent-and

royalty-free, general-purpose compressed audio format.

 

Will Drewry of the Google Security Team reported several flaws in the way

libvorbis processed audio data. An attacker could create a carefully

crafted OGG audio file in such a way that it could cause an application

linked with libvorbis to crash, or execute arbitrary code when it was

opened. (CVE-2008-1419, CVE-2008-1420, CVE-2008-1423, CVE-2008-2009)

 

Moreover, additional OGG file sanity-checks have been added to prevent

possible exploitation of similar issues in the future.

 

Users of libvorbis are advised to upgrade to these updated packages, which

contain backported patches to resolve these issues.
