libsndfile vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 ESM

Summary:

libsndfile could be made to crash or expose sensitive information
if it received specially crafted input.

Software Description:

Details:

It was discovered that libsndfile was incorrectly performing memory
management operations and incorrectly using buffers when executing
its FLAC codec. If a user or automated system were tricked into
processing a specially crafted sound file, an attacker could

sensitive information.
