Severity: Low · CVSS 3.3CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L
Published: Oct 15, 2018, 2:29:00 AM UTC

EPSS: 1.82% · Oct 25, 2026

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. An invalid memory address dereference was discovered in read_reloc in reloc.c. The vulnerability causes a segmentation fault and application crash, which leads to denial of service, as demonstrated by objdump, because of missing _bfd_clear_contents bounds checking.
