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