15 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
