Ubuntu Security Notice USN-3604-1
March 22, 2018

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:
libvorbis0a 1.3.5-3ubuntu0.2

Ubuntu 14.04 LTS:
libvorbis0a 1.3.2-1.3ubuntu1.2

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