Synopsis |
| 16 |
======== |
| 17 |
|

| 19 |
arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
VLC is a cross-platform media player and streaming server. |
| 25 |
|
| 26 |

Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Tobias Klein reported the following vulnerabilities: |
| 38 |
|
| 39 |
* A stack-based buffer overflow when processing CUE image files in |
| 40 |
modules/access/vcd/cdrom.c (CVE-2008-5032). |
| 41 |
|
| 42 |
* A stack-based buffer overflow when processing RealText (.rt) |
| 43 |
subtitle files in the ParseRealText() function in |
| 44 |
modules/demux/subtitle.c (CVE-2008-5036). |
| 45 |
|
| 46 |
* An integer overflow when processing RealMedia (.rm) files in the |
| 47 |
ReadRealIndex() function in real.c in the Real demuxer plugin, |
| 48 |
leading to a heap-based buffer overflow (CVE-2008-5276). |
| 49 |
|
| 50 |
Impact |
| 51 |
====== |
| 52 |
|
| 53 |
A remote attacker could entice a user to open a specially crafted CUE |
| 54 |
image file, RealMedia file or RealText subtitle file, possibly |
| 55 |
resulting in the execution of arbitrary code with the privileges of the |
| 56 |
user running the application. |
| 57 |
|
| 58 |
Workaround |
| 59 |
========== |
| 60 |
|
| 61 |
There is no known workaround at this time. |
| 62 |
|
| 63 |
Resolution |
| 64 |
========== |
| 65 |
|
| 66 |
All VLC users should upgrade to the latest version: |
| 67 |
|
| 68 |
# emerge --sync |
| 69 |
# emerge --ask --oneshot --verbose ">=media-video/vlc-0.9.8a" |
| 70 |
