Description |
36 |
=========== |
37 |
|
38 |
xine-lib does not check boundaries on data being read into buffers from |
39 |
DMO video files in code that is shared with MPlayer |
40 |
(DMO_VideoDecoder.c). |
41 |
|
42 |
Impact |
43 |
====== |
44 |
|
45 |
An attacker could entice a user to play a specially crafted DMO video |
46 |
file with a player using xine-lib, potentially resulting in the |
47 |
execution of arbitrary code with the privileges of the user running the |
48 |
player. |
49 |
|
50 |
Workaround |
51 |
========== |
52 |
|
53 |
There is no known workaround at this time. |
54 |
|
55 |
Resolution |
56 |
========== |
57 |
|
58 |
All xine-lib users on the x86 platform should upgrade to the latest |
59 |
version: |
60 |
|
61 |
# emerge --sync |
62 |
# emerge --ask --oneshot --verbose ">=media-libs/xine-lib-1.1.4-r2" |
