CVE-2020-35448

LOW3.3

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.

MEDIUM5.5

A flaw was found in GNU Binutils 2.35.1, where there is a heap-based buffer overflow in _bfd_elf_slurp_secondary_reloc_section in elf.c due to the number of symbols not calculated correctly. The highest threat from this vulnerability is to system availability.

HIGH7.8

A flaw was found in binutils readelf 2.35 program. An attacker who is able to convince a victim using readelf to read a crafted file could trigger a stack buffer overflow, out-of-bounds write of arbitrary data supplied by the attacker. The highest impact of this flaw is to confidentiality, integrity, and availability.
