How to fix?

Upgrade Centos:7 libtiff to version 0:4.0.3-35.el7 or higher.

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.

_TIFFCheckMalloc and _TIFFCheckRealloc in tif_aux.c in LibTIFF through 4.0.10 mishandle Integer Overflow checks because they rely on compiler behavior that is undefined by the applicable C standards. This can, for example, lead to an application crash.
