Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A heap overflow in MPlayer might lead to the execution of arbitrary |
| 19 |
code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
MPlayer is a media player capable of handling multiple multimedia file |
| 25 |
formats. |
| 26 |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Sven Tantau discovered a heap overflow in the code handling the strf |
| 39 |
chunk of PCM audio streams. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
An attacker could craft a malicious video or audio file which, when |
| 45 |
opened using MPlayer, would end up executing arbitrary code on the |
| 46 |
victim's computer with the permissions of the user running MPlayer. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
You can mitigate the issue by adding "ac=-pcm," to your MPlayer |
| 52 |
configuration file (note that this will prevent you from playing |
| 53 |
uncompressed audio). |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All MPlayer users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0_pre7-r1" |
| 62 |
