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

NVD Description

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

libtiff's tiffcrop tool has a uint32_t underflow which leads to out of bounds read and write in the extractContigSamples8bits routine. An attacker who supplies a crafted file to tiffcrop could trigger this flaw, most likely by tricking a user into opening the crafted file with tiffcrop. Triggering this flaw could cause a crash or potentially further exploitation.
