KDE Security Advisory: start_kdeinit multiple vulnerabilities
Original Release Date: 2008-04-26
URL: http://www.kde.org/info/security/advisory-20080426-2.txt
0. References
CVE-2008-1671
1. Systems affected:
start_kdeinit of KDE 3.x as of KDE 3.5.5 or newer. KDE 4.0
and newer is not affected. Only Linux platform is affected.
2. Overview:
start_kdeinit is a wrapper to launch kdeinit with a lower OOM
score on Linux. This helper is used to ensure that a
single KDE application triggering the Linux kernel OOM killer
does not kill the whole KDE session. By default,
start_kdeinit is installed as setuid root. The start_kdeinit
processing of user-influenceable input is faulty.
3. Impact:
If start_kdeinit is installed as setuid root, a local user
might be able to send unix signals to other processes, cause
a denial of service or even possibly execute arbitrary code.
4. Solution:
Source code patches have been made available which fix these
vulnerabilities. Contact your OS vendor / binary package provider
for information about how to obtain updated binary packages.
5. Patch:
A patch for KDE 3.5.5 - KDE 3.5.9 is available from
ftp://ftp.kde.org/pub/kde/security_patches :
