Gentoo Linux Security Advisory

Title: VLC: Multiple vulnerabilities (GLSA 200803-13)
Severity: high
Exploitable: remote
Date: March 07, 2008
Bug(s): #203345, #211575, #205299
ID: 200803-13

Synopsis


Multiple vulnerabilities were found in VLC, allowing for the execution of
arbitrary code and Denial of Service.


Background


VLC is a cross-platform media player and streaming server.


Affected Packages

Package: media-video/vlc
Vulnerable: < 0.8.6e
Unaffected: >= 0.8.6e
Architectures: All supported architectures


Description


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.


Resolution


All VLC users should upgrade to the latest version:
