RHSA-2006:0648 - Security Advisory

Topic

Updated kdegraphics packages that fix several security flaws in kfax are
now available for Red Hat Enterprise Linux 2.1, and 3.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description

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.
