Multiple vulnerabilities were found in VLC, allowing for the execution of
arbitrary code and Denial of Service.
VLC is a cross-platform media player and streaming server.
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
- 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).
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).
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
There is no known workaround at this time.
All VLC users should upgrade to the latest version:
