1. Summary:

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

The Red Hat Security Response Team has rated this update as having Moderate
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.

2. Relevant releases/architectures:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

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

A heap-based buffer overflow and a use-after-free flaw 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. (CVE-2013-1960, CVE-2013-4232)

Multiple buffer overflow flaws were found in the gif2tiff tool. An attacker
could use these flaws to create a specially crafted GIF file that could
cause gif2tiff to crash or, possibly, execute arbitrary code.
(CVE-2013-4231, CVE-2013-4243, CVE-2013-4244)

Multiple buffer overflow flaws 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. (CVE-2013-1961)

Red Hat would like to thank Emmanuel Bouillon of NCI Agency for reporting
CVE-2013-1960 and CVE-2013-1961. The CVE-2013-4243 issue was discovered by
Murray McAllister of the Red Hat Security Response Team, and the
CVE-2013-4244 issue was discovered by Huzaifa Sidhpurwala of the Red Hat
Security Response Team.

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