Trixter Jack discovered an array indexing error in the
|
|
get_intra_block() function in the file src/bitstream/mbcoding.c. The
|
|
get_inter_block_h263() and get_inter_block_mpeg() functions in the same
|
|
file were also reported as vulnerable.
|
|
</p>

<impact type="normal">
|
|
<p>
|
|
An attacker could exploit these vulnerabilities to execute arbitrary
|
|
code by tricking a user or automated system into processing a malicious
|
|
video file with an application that makes use of the Xvid library.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Xvid users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-libs/xvid-1.1.3"</code>
|
