How to fix?

There is no fixed version for RHEL:7 libtiff-tools.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libtiff-tools package and not the libtiff-tools package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

Null source pointer passed as an argument to memcpy() function within TIFFReadDirectory() in tif_dirread.c in libtiff versions from 4.0 to 4.3.0 could lead to Denial of Service via crafted TIFF file. For users that compile libtiff from sources, a fix is available with commit 561599c.
