Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
xine-lib contains several vulnerabilities potentially allowing the |
| 22 |
execution of arbitrary code. |
| 23 |
|
| 24 |
Background |
| 25 |
========== |
| 26 |
|
| 27 |
xine-lib is a multimedia library which can be utilized to create |
| 28 |
multimedia frontends. |
| 29 |
|
| 30 |
Affected packages |
| 31 |
================= |
| 32 |
|
| 33 |
------------------------------------------------------------------- |
| 34 |
Package / Vulnerable / Unaffected |
| 35 |
------------------------------------------------------------------- |
| 36 |
1 media-libs/xine-lib <= 1_rc5-r3 >= 1_rc6 |
| 37 |
|
| 38 |
Description |
| 39 |
=========== |
| 40 |
|
| 41 |
xine-lib contains two stack-based overflows and one heap-based |
| 42 |
overflow. In the code reading VCD disc labels, the ISO disc label is |
| 43 |
copied into an unprotected stack buffer of fixed size. Also, there is a |
| 44 |
buffer overflow in the code that parses subtitles and prepares them for |
| 45 |
display (XSA-2004-4). Finally, xine-lib contains a heap-based overflow |
| 46 |
in the DVD sub-picture decoder (XSA-2004-5). |
| 47 |
|
| 48 |
(Please note that the VCD MRL issue mentioned in XSA-2004-4 was fixed |
| 49 |
with GLSA 200408-18.) |
| 50 |
|
| 51 |
Impact |
| 52 |
====== |
| 53 |
|
| 54 |
With carefully-crafted VCDs, DVDs, MPEGs or subtitles, an attacker may |
| 55 |
cause xine-lib to execute arbitrary code with the permissions of the |
| 56 |
user. |
| 57 |
|
| 58 |
Workaround |
| 59 |
========== |
| 60 |
|
| 61 |
There is no known workaround at this time. |
| 62 |
|
| 63 |
Resolution |
| 64 |
========== |
| 65 |
|
| 66 |
All xine-lib users should upgrade to the latest version: |
| 67 |
|
| 68 |
# emerge sync |
| 69 |
|
| 70 |
# emerge -pv ">=media-libs/xine-lib-1_rc6" |
| 71 |
# emerge ">=media-libs/xine-lib-1_rc6" |
| 72 |
|
