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:
- libsndfile: Library for reading/writing audio files
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
possibly use this issue to cause a denial of service or obtain
sensitive information.
Update instructions:
The problem can be corrected by updating your system to the following

Ubuntu 16.04 ESM:
libsndfile1 1.0.25-10ubuntu0.16.04.3+esm2
