kdegraphics security update

CentOS Errata and Security Advisory CESA-2006:0648

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)

Red Hat Enterprise 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.
