<p>
FFmpeg is a complete solution to record, convert and stream audio and
video. gst-plugins-ffmpeg is a FFmpeg based gstreamer plugin which
includes a vulnerable copy of FFmpeg code. Mplayer is a multimedia
player which also includes a vulnerable copy of the code.
</p>

<description>
<p>
Multiple vulnerabilities were found in FFmpeg:
</p>
<ul><li>astrange
reported a stack-based buffer overflow in the str_read_packet() in
libavformat/psxstr.c when processing .str files (CVE-2008-3162).</li>
<li>Multiple buffer overflows in libavformat/utils.c
(CVE-2008-4866).</li>
<li>A buffer overflow in libavcodec/dca.c
(CVE-2008-4867).</li>
<li>An unspecified vulnerability in the
avcodec_close() function in libavcodec/utils.c (CVE-2008-4868).</li>
<li>Unspecified memory leaks (CVE-2008-4869).</li>
<li>Tobias Klein
repoerted a NULL pointer dereference due to an integer signedness error
in the fourxm_read_header() function in libavformat/4xm.c
(CVE-2009-0385).</li>
</ul>
</description>
<impact type="normal">
<p>
A remote attacker could entice a user to open a specially crafted media
file, possibly leading to the execution of arbitrary code with the
privileges of the user running the application, or a Denial of Service.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All FFmpeg users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/ffmpeg-0.4.9_p20090201"</code>
<p>
All gst-plugins-ffmpeg users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-plugins/gst-plugins-ffmpeg-0.10.5"</code>
<p>
All Mplayer users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0_rc2_p28450"</code>
