CVE-2017-17080 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-17080):
  elf.c in the Binary File Descriptor (BFD) library (aka libbfd), as
  distributed in GNU Binutils 2.29.1, does not validate sizes of core notes,
  which allows remote attackers to cause a denial of service (bfd_getl32
  heap-based buffer over-read and application crash) via a crafted object
  file, related to elfcore_grok_netbsd_procinfo,
  elfcore_grok_openbsd_procinfo, and elfcore_grok_nto_status.
