RHSA-2006:0603 - Security Advisory

Topic

Updated libtiff packages that fix several security flaws are now available
for Red Hat Enterprise Linux.

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

Description

The libtiff package contains a library of functions for manipulating TIFF
(Tagged Image File Format) files.

Tavis Ormandy of Google discovered a number of flaws in libtiff during a
security audit. An attacker could create a carefully crafted TIFF file in
such a way that it was possible to cause an application linked with libtiff
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)

All users are advised to upgrade to these updated packages, which contain
backported fixes for these issues.
