How to fix?

Upgrade SLES:15.0 libtiff5 to version 4.0.9-5.20.1 or higher.

NVD Description

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

The TIFFReadDirEntryArray function in tif_read.c in LibTIFF 4.0.8 mishandles memory allocation for short files, which allows remote attackers to cause a denial of service (allocation failure and application crash) in the TIFFFetchStripThing function in tif_dirread.c during a tiff2pdf invocation.
