Synopsis
Multiple vulnerabilities in libvorbis might lead to the execution of
arbitrary code.
2.
Impact Information
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.
Description
Will Drewry of the Google Security Team reported multiple
vulnerabilities in libvorbis:
-
A zero value for "codebook.dim" is not properly handled, leading to a
crash, infinite loop or triggering an integer overflow
(CVE-2008-1419).
-
An integer overflow in "residue partition value" evaluation might lead
to a heap-based buffer overflow (CVE-2008-1420).
-
An integer overflow in a certain "quantvals" and "quantlist"
calculation might lead to a heap-based buffer overflow
(CVE-2008-1423).
Impact
A remote attacker could exploit these vulnerabilities by enticing a
user to open a specially crafted Ogg Vorbis file or network stream with
an application using libvorbis. This might lead to the execution of
arbitrary code with the privileges of the user playing the file or a
Denial of Service by a crash or CPU consumption.
3.
Resolution Information
Workaround
There is no known workaround at this time.
Resolution
All libvorbis users should upgrade to the latest version:
Code Listing 3.1: Resolution |
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/libvorbis-1.2.1_rc1"
|
