==========================================================================

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

- Ubuntu 17.04
- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in libsndfile.

Software Description:
- libsndfile: Library for reading/writing audio files

Details:

Agostino Sarubbo and Jakub Jirasek 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.
