Overview

Affected versions of this package are vulnerable to Out-of-bounds Write. 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.

Remediation

There is no fixed version for binutils.
