Description Sam Fowler 2017-12-11 07:13:39 UTC

The pal2rgb tool (tools/pal2rgb.c) in LibTIFF 4.0.9 is vulnerable to a heap-based bufferflow when parsing a specially crafted .tif file. A remote attacker could exploit this to cause an application crash (denial of service) or other possible unspecified impact.
