<title>xine-lib: User-assisted execution of arbitrary code</title>
<synopsis>
xine-lib is vulnerable to multiple buffer overflows when processing FLAC
and ASF streams.

<p>
xine-lib is the core library package for the xine media player.

<description>
<p>
Damian Frizza and Alfredo Ortega (Core Security Technologies)
discovered a stack-based buffer overflow within the open_flac_file()
function in the file demux_flac.c when parsing tags within a FLAC file
(CVE-2008-0486). A buffer overflow when parsing ASF headers, which is
similar to CVE-2006-1664, has also been discovered (CVE-2008-1110).
</p>
</description>
<impact type="normal">
<p>
A remote attacker could entice a user to play specially crafted FLAC or
ASF video streams with a player using xine-lib, potentially resulting
in the execution of arbitrary code with the privileges of the user
running the player.
</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 ">=media-libs/xine-lib-1.1.10.1"</code>
</resolution>
