Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Multiple vulnerabilities were found in VLC: |
| 38 |
|
| 39 |
* Luigi Auriemma discovered that the stack-based buffer overflow when |
| 40 |
reading subtitles, which has been reported as CVE-2007-6681 in GLSA |
| 41 |
200803-13, was not properly fixed (CVE-2008-1881). |
| 42 |
|
| 43 |
* Alin Rad Pop of Secunia reported an array indexing vulnerability in |
| 44 |
the sdpplin_parse() function when processing streams from RTSP |
| 45 |
servers in Xine code, which is also used in VLC (CVE-2008-0073). |
| 46 |
|
| 47 |
* Drew Yao and Nico Golde reported an integer overflow in the |
| 48 |
MP4_ReadBox_rdrf() function in the file libmp4.c leading to a |
| 49 |
heap-based buffer overflow when reading MP4 files (CVE-2008-1489). |
| 50 |
|
| 51 |
* Drew Yao also reported integer overflows in the MP4 demuxer, the |
| 52 |
Real demuxer and in the Cinepak codec, which might lead to buffer |
| 53 |
overflows (CVE-2008-1768). |
| 54 |
|
| 55 |
* Drew Yao finally discovered and a boundary error in Cinepak, which |
| 56 |
might lead to memory corruption (CVE-2008-1769). |

Impact |
| 59 |
====== |
| 60 |
|
| 61 |
A remote attacker could entice a user to open a specially crafted media |
| 62 |
file or stream, possibly resulting in the remote execution of arbitrary |
| 63 |
code. |
| 64 |
|
| 65 |
Workaround |
| 66 |
========== |
| 67 |
|
| 68 |
There is no known workaround at this time. |
| 69 |
|
| 70 |
Resolution |
| 71 |
========== |
| 72 |
|
| 73 |
All VLC users should upgrade to the latest version: |
| 74 |
|
| 75 |
# emerge --sync |
| 76 |
# emerge --ask --oneshot --verbose ">=media-video/vlc-0.8.6f" |
| 77 |
