CVE-2016-3945

Status Candidate

Overview

Multiple integer overflows in the (1) cvt_by_strip and (2) cvt_by_tile functions in the tiff2rgba tool in LibTIFF 4.0.6 and earlier, when -b mode is enabled, allow remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted TIFF image, which triggers an out-of-bounds write.

Red Hat Security Advisory 2016-1547-01 - The libtiff packages contain a library of functions for manipulating Tagged Image File Format files. Security Fix: Multiple flaws have been discovered in libtiff. A remote attacker could exploit these flaws to cause a crash or memory corruption and, possibly, execute arbitrary code by tricking an application linked against libtiff into processing specially crafted files.
