Updated kdegraphics packages that fix several security flaws in kfax are now available for CentOS Linux 2.1, and 3. This update has been rated as having moderate security impact by the Red Hat Security Response Team.
The kdegraphics package contains graphics applications for the K Desktop Environment. Tavis Ormandy of Google discovered a number of flaws in libtiff during a security audit. The kfax application contains a copy of the libtiff code used for parsing TIFF files and is therefore affected by these flaws. An attacker who has the ability to trick a user into opening a malicious TIFF file could cause kfax to crash or possibly execute arbitrary code. (CVE-2006-3459, CVE-2006-3460, CVE-2006-3461, CVE-2006-3462, CVE-2006-3463, CVE-2006-3464, CVE-2006-3465) CentOS Linux 4 is not vulnerable to these issues as kfax uses the shared libtiff library which has been fixed in a previous update. Users of kfax should upgrade to these updated packages, which contain backported patches and are not vulnerable to this issue.
