How to fix?

Upgrade SLES:15.0 libctf0 to version 2.37-6.23.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libctf0 package and not the libctf0 package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.35.1. A heap-based buffer over-read can occur in bfd_getl_signed_32 in libbfd.c because sh_entsize is not validated in _bfd_elf_slurp_secondary_reloc_section in elf.c.
