==========================================================================
Ubuntu Security Notice USN-5409-1
May 10, 2022

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
package versions:

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

In general, a standard system update will make all the necessary changes.
