How to fix?

Upgrade SLES:15.2 binutils-devel-32bit to version 2.35-7.11.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream binutils-devel-32bit package and not the binutils-devel-32bit package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. There is a heap-based buffer over-read in _bfd_doprnt in bfd.c because elf_object_p in elfcode.h mishandles an e_shstrndx section of type SHT_GROUP by omitting a trailing '\0' character.
