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) 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.
