Descriptions

LibTIFF 4.4.0 has an out-of-bounds read in tiffcp in tools/tiffcp.c:948, allowing attackers to cause a denial-of-service via a crafted tiff file. For users that compile libtiff from sources, the fix is available with commit e8131125.

A flaw was found in tiffcp, a program distributed by the libtiff package. A specially crafted tiff file can lead to an out-of-bounds read in the tiffcp function in tools/tiffcp.c, resulting in a denial of service and limited information disclosure.

The libtiff packages contain a library of functions for manipulating Tagged Image File Format files. Issues addressed include buffer overflow, integer overflow, out of bounds read, and out of bounds write vulnerabilities.
