Details

USN-4336-1 fixed several vulnerabilities in GNU binutils. This update provides
the corresponding update for Ubuntu 16.04 ESM.

Original advisory details:

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.
