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 : 9d99d5f02b696e7a493836f285a319da post-kde-3.5.5-kinit.diff - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
