NVD Description

Note: Versions mentioned in the description apply only to the upstream libtiff5-32bit package and not the libtiff5-32bit package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

A NULL pointer dereference in the function _TIFFmemcmp at tif_unix.c (called from TIFFWriteDirectoryTagTransferfunction) in LibTIFF 4.0.9 allows an attacker to cause a denial-of-service through a crafted tiff file. This vulnerability can be triggered by the executable tiffcp.
