Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
MPlayer is vulnerable to integer overflows in FFmpeg and ASF decoding |
| 19 |
that could potentially result in the execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
MPlayer is a media player capable of handling multiple multimedia file |
| 25 |
formats. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 media-video/mplayer < 1.0.20060217 >= 1.0.20060217 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
MPlayer makes use of the FFmpeg library, which is vulnerable to a heap |
| 39 |
overflow in the avcodec_default_get_buffer() function discovered by |
| 40 |
Simon Kilvington (see GLSA 200601-06). Furthermore, AFI Security |
| 41 |
Research discovered two integer overflows in ASF file format decoding, |
| 42 |
in the new_demux_packet() function from libmpdemux/demuxer.h and the |
| 43 |
demux_asf_read_packet() function from libmpdemux/demux_asf.c. |
| 44 |
|
| 45 |
Impact |
| 46 |
====== |
| 47 |
|
| 48 |
An attacker could craft a malicious media file which, when opened using |
| 49 |
MPlayer, would lead to a heap-based buffer overflow. This could result |
| 50 |
in the execution of arbitrary code with the permissions of the user |
| 51 |
running MPlayer. |
| 52 |
|
| 53 |
Workaround |
| 54 |
========== |
| 55 |
|
| 56 |
There is no known workaround at this time. |
| 57 |
|
| 58 |
Resolution |
| 59 |
========== |
| 60 |
|
| 61 |
All MPlayer users should upgrade to the latest version: |
| 62 |
|
| 63 |
# emerge --sync |
| 64 |
# emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0.20060217" |
| 65 |
|
