This script is Copyright (C) 2012-2017 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated libtiff packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

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

libtiff did not properly convert between signed and unsigned integer
values, leading to a buffer overflow. 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-2012-2088)

Multiple integer overflow flaws, leading to heap-based buffer
overflows, were found in the tiff2pdf tool. An attacker could use
these flaws to create a specially crafted TIFF file that would cause
tiff2pdf to crash or, possibly, execute arbitrary code.

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