GLSA-200803-13 : VLC: Multiple vulnerabilities
Critical Nessus Plugin ID 31439
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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).
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.
There is no known workaround at this time.
SolutionAll VLC users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-video/vlc-0.8.6e'
