|
21 |
Background |
22 |
========== |
23 |
|
24 |

Description |
35 |
=========== |
36 |
|
37 |
Damian Frizza and Alfredo Ortega (Core Security Technologies) |
38 |
discovered a stack-based buffer overflow within the open_flac_file() |
39 |
function in the file demux_flac.c when parsing tags within a FLAC file |
40 |
(CVE-2008-0486). A buffer overflow when parsing ASF headers, which is |
41 |
similar to CVE-2006-1664, has also been discovered. |
42 |
|
43 |
Impact |
44 |
====== |
45 |
|
46 |
A remote attacker could entice a user to play specially crafted FLAC or |
47 |
ASF video streams with a player using xine-lib, potentially resulting |
48 |
in the execution of arbitrary code with the privileges of the user |
49 |
running the player. |
50 |
|
51 |
Workaround |
52 |
========== |
53 |
|
54 |
There is no known workaround at this time. |
55 |
|
56 |
Resolution |
57 |
========== |
58 |
|
59 |
All xine-lib users should upgrade to the latest version: |
60 |
|
61 |
# emerge --sync |
62 |
# emerge --ask --oneshot --verbose ">=media-libs/xine-lib-1.1.10.1" |
63 |
