Updated kdelibs packages that fix a flaw in kimgio input validation are now available for CentOS Linux 4. This update has been rated as having important security impact by the Red Hat Security Response Team.
KDE is a graphical desktop environment for the X Window System. Konqueror is the file manager for the K Desktop Environment. A source code audit performed by the KDE security team discovered several vulnerabilities in the PCX and other image file format readers. A buffer overflow was found in the kimgio library for KDE 3.4.0. An attacker could create a carefully crafted PCX image in such a way that it would cause kimgio to execute arbitrary code when processing the image. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1046 to this issue. All users of kdelibs should upgrade to these updated packages, which contain a backported security patch to correct these issues.
