Background ========= KDE is a feature-rich graphical desktop environment for Linux and Unix-like Operating Systems. DCOP is KDE's simple IPC/RPC mechanism. dcopidlng is a DCOP helper script. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 kde-base/kdelibs < 3.3.2-r5 > = 3.3.2-r5 *> = 3.2.3-r7 Description ========== Davide Madrisan has discovered that the dcopidlng script creates temporary files in a world-writable directory with predictable names. Impact ===== A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When dcopidlng is executed, this would result in the file being overwritten with the rights of the user running the utility, which could be the root user. Workaround ========= There is no known workaround at this time. Resolution ========= All kdelibs users should upgrade to the latest version: # emerge--sync # emerge --ask --oneshot --verbose kde-base/kdelibs References ========= [ 1 ] CAN-2005-0365 https://www.cve.org/CVERecord?id=CVE-CAN-2005-0365 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200503-14 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
