Synopsis
========
A processing error in libvorbis might result in the execution of
arbitrary code or a Denial of Service.
Background
==========
libvorbis is the reference implementation of the Xiph.org Ogg Vorbis
audio file format. It is used by many applications for playback of Ogg
Vorbis files.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/libvorbis lt; 1.2.3 gt;= 1.2.3
Description
===========
Lucas Adamski reported that libvorbis does not correctly process file
headers, related to static mode headers and encoding books.
Impact
======
A remote attacker could entice a user to play a specially crafted OGG
Vorbis file using an application that uses libvorbis, possibly
resulting in the execution of arbitrary code with the privileges of the
user running the application, or a Denial of Service.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All libvorbis users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose =media-libs/libvorbis-1.2.3
References
==========
