There is no fixed version for Centos:7 libtiff.

NVD Description

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

In LibTIFF 4.0.9, there is a NULL pointer dereference in the TIFFWriteDirectorySec function in tif_dirwrite.c that will lead to a denial of service attack, as demonstrated by tiffset.
