	<p>Tobias Klein from TrapKit notifies:</p>
	<blockquote cite="http://www.trapkit.de/advisories/TKADV2008-010.txt">
	  <p>The VLC media player contains a stack overflow
	  vulnerability while parsing malformed TiVo ty media files.
	  The vulnerability can be trivially exploited by a (remote)
	  attacker to execute arbitrary code in the context of VLC
	  media player.</p>

	<p>Entry for CVE-2008-4686 says:</p>
	<blockquote cite="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4686">
	  <p>Multiple integer overflows in ty.c in the TY demux
	  plugin (aka the TiVo demuxer) in VideoLAN VLC media player,
	  probably 0.9.4, allow remote attackers to have an unknown
	  impact via a crafted .ty file, a different vulnerability
	  than CVE-2008-4654.</p>

I had traced the vulnerable code down to the 0.9.0.20080223: older
snapshots have no such code as referenced in the commits
