libvorbis vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 17.10
– Ubuntu 16.04 LTS
– Ubuntu 14.04 LTS
Summary:
libvorbis could be made to crash or run programs as your login if it
opened a specially crafted file.
Software Description:
– libvorbis: The Vorbis General Audio Compression Codec
Details:
Richard Zhu discovered that libvorbis incorrectly handled certain sound
files. An attacker could use this to cause libvorbis to crash, resulting in
a denial or service, or possibly execute arbitrary code.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 17.10:
libvorbis0a 1.3.5-4ubuntu0.2
Ubuntu 16.04 LTS:

After a standard system upgrade you need to restart any applications that
use libvorbis, such as Totem and gtkpod, to effect the necessary changes.
