The SLES security team deemed this advisory irrelevant for SLES:15.1.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libelf-devel-32bit package and not the libelf-devel-32bit package as distributed by SLES.
Divide-by-zero vulnerabilities in the function arlib_add_symbols() in arlib.c in elfutils 0.174 allow remote attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by eu-ranlib, because a zero sh_entsize is mishandled.
