Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
Multiple vulnerabilities were found in VLC, allowing for the execution |
| 22 |
of arbitrary code and Denial of Service. |
| 23 |
|
| 24 |
Background |
| 25 |
========== |
| 26 |
|
| 27 |
VLC is a cross-platform media player and streaming server. |

Description |
| 38 |
=========== |
| 39 |
|
| 40 |
Multiple vulnerabilities were found in VLC: |
| 41 |
|
| 42 |
* Michal Luczaj and Luigi Auriemma reported that VLC contains |
| 43 |
boundary errors when handling subtitles in the ParseMicroDvd(), |
| 44 |
ParseSSA(), and ParseVplayer() functions in the |
| 45 |
modules/demux/subtitle.c file, allowing for a stack-based buffer |
| 46 |
overflow (CVE-2007-6681). |
| 47 |
|
| 48 |
* The web interface listening on port 8080/tcp contains a format |
| 49 |
string error in the httpd_FileCallBack() function in the |
| 50 |
network/httpd.c file (CVE-2007-6682). |
| 51 |
|
| 52 |
* The browser plugin possibly contains an argument injection |
| 53 |
vulnerability (CVE-2007-6683). |
| 54 |
|
| 55 |
* The RSTP module triggers a NULL pointer dereference when processing |
| 56 |
a request without a "Transport" parameter (CVE-2007-6684). |
| 57 |
|
| 58 |
* Luigi Auriemma and Remi Denis-Courmont found a boundary error in |
| 59 |
the modules/access/rtsp/real_sdpplin.c file when processing SDP data |
| 60 |
for RTSP sessions (CVE-2008-0295) and a vulnerability in the |
| 61 |
libaccess_realrtsp plugin (CVE-2008-0296), possibly resulting in a |
| 62 |
heap-based buffer overflow. |
| 63 |
|
| 64 |
* Felipe Manzano and Anibal Sacco (Core Security Technologies) |
| 65 |
discovered an arbitrary memory overwrite vulnerability in VLC's |
| 66 |
MPEG-4 file format parser (CVE-2008-0984). |
| 67 |
|
| 68 |
Impact |
| 69 |
====== |
| 70 |
|
| 71 |
A remote attacker could send a long subtitle in a file that a user is |
| 72 |
enticed to open, a specially crafted MP4 input file, long SDP data, or |
| 73 |
a specially crafted HTTP request with a "Connection" header value |
| 74 |
containing format specifiers, possibly resulting in the remote |
| 75 |
execution of arbitrary code. Also, a Denial of Service could be caused |
| 76 |
and arbitrary files could be overwritten via the "demuxdump-file" |
| 77 |
option in a filename in a playlist or via an EXTVLCOPT statement in an |
| 78 |
MP3 file. |
| 79 |
|
| 80 |
Workaround |
| 81 |
========== |
| 82 |
|
| 83 |
There is no known workaround at this time. |
| 84 |
|
| 85 |
Resolution |
| 86 |
========== |
| 87 |
|
| 88 |
All VLC users should upgrade to the latest version: |
| 89 |
|
| 90 |
# emerge --sync |
| 91 |
# emerge --ask --oneshot --verbose ">=media-video/vlc-0.8.6e" |
| 92 |
