wavpack vulnerability
==========================================================================

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

- Ubuntu 16.04 ESM

Summary:

WavPack could be made to crash if it opened a specially crafted
file.

Software Description:
- wavpack: audio codec (lossy and lossless) - encoder and decoder

Details:

It was discovered that WavPack was not properly performing checks
when dealing with memory. If a user were tricked into decompressing a
specially crafted WavPack Audio File, an attacker could possibly use
this issue to cause the WavPack decompressor to crash, resulting in a
denial of service.

Update instructions:

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

Ubuntu 16.04 ESM:
   libwavpack1                     4.75.2-2ubuntu0.2+esm1
   wavpack                         4.75.2-2ubuntu0.2+esm1

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