(RHSA-2006:0603) libtiff security update

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.
