Gentoo Linux Security Advisory

Title: libvorbis: User-assisted execution of arbitrary code (GLSA 200909-02)
Severity: normal
Exploitable: remote
Date: September 07, 2009
Bug(s): #280590
ID: 200909-02

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: media-libs/libvorbis
Vulnerable: < 1.2.3
Unaffected: >= 1.2.3
Architectures: All supported architectures


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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/libvorbis-1.2.3"


References

CVE-2009-2663
