Last modified Jun 17, 2026

CVE-2020-35448 is a low-severity vulnerability rated 3.3/10 on the CVSS scale. 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.. EPSS estimates a 1.28% chance of exploitation in the next 30 days.
