Title: GNU binutils vulnerabilities
Summary: Several security issues were fixed in GNU binutils.
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.
Instructions: In general, a standard system update will make all the necessary changes.

## Abstract
Fuzzing has become the de facto standard technique for finding software vulnerabilities. However, even state-of-the-art fuzzers are not very efficient at finding hard-to-trigger software bugs. Most popular fuzzers use evolutionary guidance to generate inputs that can trigger different bugs. Such evolutionary algorithms, while fast and simple to implement, often get stuck in fruitless sequences of random mutations. Gradient-guided optimization presents a promising alternative to evolutionary guidance. Gradient-guided techniques have been shown to significantly outperform evolutionary algorithms at solving hig
