How to fix?

Upgrade Debian:13 binutils to version 2.37-3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream binutils package and not the binutils package as distributed by Debian. See How to fix? for Debian:13 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.
