Updated libtiff packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 6.
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)
A flaw was found in the way libtiff handled OJPEG-encoded TIFF images. An
attacker could use this flaw to create a specially crafted TIFF file that
would cause an application using libtiff to crash. (CVE-2010-2596)
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)
