Synopsis |

======== |

|
21 |
Multiple vulnerabilities were found in VLC, allowing for the execution |
22 |
of arbitrary code and Denial of Service. |

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" |
