libsndfile vulnerability

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

libsndfile could be made to crash or run programs as your login if it

USN-5025-1 fixed a vulnerability in libsndfile. This update provides
the corresponding update for Ubuntu 14.04 ESM and Ubuntu 16.04 ESM.

Original advisory details:

It was discovered that libsndfile incorrectly handled certain malformed
files. A remote attacker could use this issue to cause libsndfile to crash,
resulting in a denial of service, or possibly execute arbitrary code.

The problem can be corrected by updating your system to the following
package versions:
