3. Description:

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

A heap-based buffer overflow flaw was found in the way libtiff processed
certain TIFF image files that were compressed with the JPEG compression
algorithm. An attacker could use this flaw to create a specially-crafted
TIFF file that, when opened, would cause an application linked against
libtiff to crash or, possibly, execute arbitrary code. (CVE-2009-5022)

All libtiff users should upgrade to these updated packages, which contain a
backported patch to resolve this issue. All running applications linked
against libtiff must be restarted for this update to take effect.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259
