Upgrade SLES:15.0 elfutils to version 0.168-4.5.3 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream elfutils package and not the elfutils package as distributed by SLES.
See How to fix? for SLES:15.0 relevant fixed versions and status.
elflint.c in elfutils 0.168 does not validate the number of sections and the number of segments, which allows remote attackers to cause a denial of service (memory consumption) via a crafted ELF file.
