"From Red Hat Security Advisory 2011:0318 :

Updated libtiff packages that fix one security issue are now available
for Red Hat Enterprise Linux 4, 5, and 6.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.

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 Internet Fax image files, compressed with the
CCITT Group 4 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-2011-0192)

Red Hat would like to thank Apple Product Security for reporting this
issue.

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."
