Synopsis |
16 |
======== |
17 |
|
18 |
xine-lib is vulnerable to multiple heap-based buffer overflows when |
19 |
processing RTSP streams. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |

Description |
35 |
=========== |
36 |
|
37 |
Luigi Auriemma reported that xine-lib does not properly check |
38 |
boundaries when processing SDP attributes of RTSP streams, leading to |
39 |
heap-based buffer overflows. |
40 |
|
41 |
Impact |
42 |
====== |
43 |
|
44 |
An attacker could entice a user to play specially crafted RTSP video |
45 |
streams with a player using xine-lib, potentially resulting in the |
46 |
execution of arbitrary code with the privileges of the user running the |
47 |
player. |
48 |
|
49 |
Workaround |
50 |
========== |
51 |
|
52 |
There is no known workaround at this time. |
53 |
|
54 |
Resolution |
55 |
========== |
56 |
|
57 |
All xine-lib users should upgrade to the latest version: |
58 |
|
59 |
# emerge --sync |
60 |
# emerge --ask --oneshot --verbose ">=media-libs/xine-lib-1.1.9.1" |
