Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200803-13
(VLC: Multiple vulnerabilities)

Multiple vulnerabilities were found in VLC:
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).
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).
The browser plugin possibly contains an
argument injection vulnerability (CVE-2007-6683).
The RSTP
module triggers a NULL pointer dereference when processing a request
without a 'Transport' parameter (CVE-2007-6684).
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.
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).

Impact :

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.

Workaround :

There is no known workaround at this time.

Solution :

All VLC users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-video/vlc-0.8.6e'

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
