multimedia formats.

<description>
<p>
Federico L. Bossi Bonin discovered that when handling MPEG streams
xine-lib fails to make a proper boundary check of the input data
supplied by the user before copying it to an insufficiently sized
memory buffer.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could entice a user to play a specially-crafted
MPEG file, resulting in the execution of arbitrary code with the
permissions of the user running the application.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All xine-lib users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-libs/xine-lib-1.1.2_pre20060328-r1&quot;</code>
