Synopsis |
16 |
======== |
17 |
|
18 |
The artswrapper part of aRts allows local users to execute arbitrary |
19 |
code with elevated privileges. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
aRts is a real time modular system for synthesizing audio used by KDE. |
25 |
artswrapper is a helper application used to start the aRts daemon. |
26 |
|
27 |
Affected packages |
28 |
================= |
29 |
|
30 |
------------------------------------------------------------------- |
31 |
Package / Vulnerable / Unaffected |
32 |
------------------------------------------------------------------- |
33 |
1 kde-base/arts < 3.5.2-r1 >= 3.5.2-r1 |
34 |
*>= 3.4.3-r1 |
35 |
|
36 |
Description |
37 |
=========== |
38 |
|
39 |
artswrapper fails to properly check whether it can drop privileges |
40 |
accordingly if setuid() fails due to a user exceeding assigned resource |
41 |
limits. |
42 |
|
43 |
Impact |
44 |
====== |
45 |
|
46 |
Local attackers could exploit this vulnerability to execute arbitrary |
47 |
code with elevated privileges. Note that the aRts package provided by |
48 |
Gentoo is only vulnerable if the artswrappersuid USE-flag is enabled. |
49 |
|
50 |
Workaround |
51 |
========== |
52 |
|
53 |
There is no known workaround at this time. |
54 |
|
55 |
Resolution |
56 |
========== |
57 |
|
58 |
All aRts users should upgrade to the latest version: |
59 |
|
60 |
# emerge --sync |
61 |
# emerge --ask --oneshot --verbose kde-base/arts |
62 |
