(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."

"Luigi Auriemma, Alin Rad Pop, Remi Denis-Courmont, Quovodis, Guido
Landi, Felipe Manzano, Anibal Sacco and others discovered multiple
vulnerabilities in vlc, an application for playback and streaming of
audio and video. In the worst case, these weaknesses permit a remote,
unauthenticated attacker to execute arbitrary code with the privileges
of the user running vlc.

The Common Vulnerabilities and Exposures project identifies the
following eight problems :

  - CVE-2007-6681
    A buffer overflow vulnerability in subtitle handling
    allows an attacker to execute arbitrary code through the
    opening of a maliciously crafted MicroDVD, SSA or
    Vplayer file.

  - CVE-2007-6682
    A format string vulnerability in the HTTP-based remote
    control facility of the vlc application allows a remote,
    unauthenticated attacker to execute arbitrary code.

  - CVE-2007-6683
    Insecure argument validation allows a remote attacker to
    overwrite arbitrary files writable by the user running
    vlc, if a maliciously crafted M3U playlist or MP3 audio
    file is opened.

  - CVE-2008-0295, CVE-2008-0296
    Heap buffer overflows in RTSP stream and session
    description protocol (SDP) handling allow an attacker to
    execute arbitrary code if a maliciously crafted RTSP
    stream is played.

  - CVE-2008-0073
    Insufficient integer bounds checking in SDP handling
    allows the execution of arbitrary code through a
    maliciously crafted SDP stream ID parameter in an RTSP
    stream.

  - CVE-2008-0984
    Insufficient integrity checking in the MP4 demuxer
    allows a remote attacker to overwrite arbitrary memory
    and execute arbitrary code if a maliciously crafted MP4
    file is opened.

  - CVE-2008-1489
    An integer overflow vulnerability in MP4 handling allows
    a remote attacker to cause a heap buffer overflow,
    inducing a crash and possibly the execution of arbitrary
    code if a maliciously crafted MP4 file is opened."
