<p>
|
|
Multiple vulnerabilities were found in VLC:
|
|
</p>
|
|
<ul>
|
|
<li>Michal Luczaj
|
|
and Luigi Auriemma reported that VLC contains boundary errors when
|
|
handling subtitles in the ParseMicroDvd(), ParseSSA(), and
|
|
ParseVplayer() functions in the modules/demux/subtitle.c file, allowing
|
|
for a stack-based buffer overflow (CVE-2007-6681).</li>
|
|
<li>The web
|
|
interface listening on port 8080/tcp contains a format string error in
|
|
the httpd_FileCallBack() function in the network/httpd.c file
|
|
(CVE-2007-6682).</li>
|
|
<li>The browser plugin possibly contains an
|
|
argument injection vulnerability (CVE-2007-6683).</li>
|
|
<li>The RSTP
|
|
module triggers a NULL pointer dereference when processing a request
|
|
without a "Transport" parameter (CVE-2007-6684).</li>
|
|
<li>Luigi
|
|
Auriemma and Remi Denis-Courmont found a boundary error in the
|
|
modules/access/rtsp/real_sdpplin.c file when processing SDP data for
|
|
RTSP sessions (CVE-2008-0295) and a vulnerability in the
|
|
libaccess_realrtsp plugin (CVE-2008-0296), possibly resulting in a
|
|
heap-based buffer overflow.</li>
|
|
<li>Felipe Manzano and Anibal Sacco
|
|
(Core Security Technologies) discovered an arbitrary memory overwrite
|
|
vulnerability in VLC's MPEG-4 file format parser (CVE-2008-0984).</li>
|
|
</ul>
|
|
</description>
|
|
<impact type="high">
|
|
<p>
|
|
A remote attacker could send a long subtitle in a file that a user is
|
|
enticed to open, a specially crafted MP4 input file, long SDP data, or
|
|
a specially crafted HTTP request with a "Connection" header value
|
|
containing format specifiers, possibly resulting in the remote
|
|
execution of arbitrary code. Also, a Denial of Service could be caused
|
|
and arbitrary files could be overwritten via the "demuxdump-file"
|
|
option in a filename in a playlist or via an EXTVLCOPT statement in an
|
|
MP3 file.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All VLC users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-video/vlc-0.8.6e"</code>
