<description>
<p>
Multiple vulnerabilities have been reported in MPlayer:
</p>
<ul>
<li>A
stack-based buffer overflow was found in the str_read_packet() function
in libavformat/psxstr.c when processing crafted STR files that
interleave audio and video sectors (CVE-2008-3162).</li>
<li>Felipe
Andres Manzano reported multiple integer underflows in the
demux_real_fill_buffer() function in demux_real.c when processing
crafted Real Media files that cause the stream_read() function to read
or write arbitrary memory (CVE-2008-3827).</li>
<li>Tobias Klein
reported a stack-based buffer overflow in the demux_open_vqf() function
in libmpdemux/demux_vqf.c when processing malformed TwinVQ files
(CVE-2008-5616).</li>
</ul>
</description>
<impact type="normal">
<p>
A remote attacker could entice a user to open a specially crafted STR,
Real Media, or TwinVQ file to execute arbitrary code or cause a Denial of
Service.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All MPlayer users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-video/mplayer-1.0_rc2_p28058-r1 &quot;</code>
</resolution>
