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)
