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.

David Thiel of iSEC Partners discovered a heap-based buffer overflow in
|
||
|
|
the _01inverse() function in res0.c and a boundary checking error in
|
||
|
|
the vorbis_info_clear() function in info.c (CVE-2007-3106 and
|
||
|
|
CVE-2007-4029). libvorbis is also prone to several Denial of Service
|
||
|
|
vulnerabilities in form of infinite loops and invalid memory access
|
||
|
|
with unknown impact (CVE-2007-4065 and CVE-2007-4066).
|
||
|

|
<impact type="normal">
|
||
|
|
<p>
|
||
|
|
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 privileges of the user playing the file or a Denial
|
||
|
|
of Service by a crash or CPU consumption.
|
||
|
|
</p>
|
||
|
|
</impact>
|
||
|
|
<workaround>
|
||
|
|
<p>
|
||
|
|
There is no known workaround at this time.
|
||
|
|
</p>
|
||
|
|
</workaround>
|
||
|
|
<resolution>
|
||
|
|
<p>
|
||
|
|
All libvorbis users should upgrade to the latest version:
|
||
|
|
</p>
|
||
|
|
<code>
|
||
|
|
# emerge --sync
|
||
|
|
# emerge --ask --oneshot --verbose ">=media-libs/libvorbis-1.2.0"</code>
|
||
