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.

USN-4336-1 fixed several vulnerabilities in GNU binutils. This update provides the corresponding update for Ubuntu 16.04 ESM. It was discovered that GNU binutils contained a large number of security issues. If a user or automated system were tricked into processing a specially-crafted file, a remote attacker could cause GNU binutils to crash, resulting in a denial of service, or possibly execute arbitrary code. Various other issues were also addressed.
