Description: Several vulnerabilities were reported in libvorbis. A remote user can cause arbitrary code to be executed on the target user's system.
A remote user can create a specially crafted OGG audio file that, when processed by the target application, will trigger an integer
overflow, heap overflow, or memory corruption error and crash or execute arbitrary code on the target system. The code will run
with the privileges of the target application.
Will Drewry of the Google Security Team reported these vulnerabilities.

Impact: A remote user can create a file that, when loaded by the target application, will execute arbitrary code on the target system.

Red Hat Security Advisory
Synopsis: Important: libvorbis security update
Advisory ID: RHSA-2008:0271-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2008-0271.html
Issue date: 2008-05-14

=====================================================================
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.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
