How to fix?

Upgrade SLES:15.0 libtiff5 to version 4.0.9-5.9.1 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.

In LibTIFF 4.0.8, there is a denial of service vulnerability in the TIFFOpen function. A crafted input will lead to a denial of service attack. During the TIFFOpen process, td_imagelength is not checked. The value of td_imagelength can be directly controlled by an input file. In the ChopUpSingleUncompressedStrip function, the _TIFFCheckMalloc function is called based on td_imagelength. If we set the value of td_imagelength close to the amount of system memory, it will hang the system or trigger the OOM killer.
