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 / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-video/vlc < 0.8.6e >= 0.8.6e
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:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-video/vlc-0.8.6e"
