wayland vulnerability
==========================================================================

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

- Ubuntu 17.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Wayland could be made to crash or run programs if it opened a specially
crafted file.

Software Description:
- wayland: Wayland compositor infrastructure

Details:

It was discovered that the Wayland Xcursor support incorrectly handled
certain files. An attacker could use these issues to cause Wayland to
crash, resulting in a denial of 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:
libwayland-cursor0 1.14.0-1ubuntu0.1

Ubuntu 16.04 LTS:
libwayland-bin 1.12.0-1~ubuntu16.04.3

libwayland-server0 1.12.0-1~ubuntu16.04.3

Ubuntu 14.04 LTS:
