Ubuntu Security Notice USN-3521-1
January 09, 2018

nvidia-graphics-drivers-384 vulnerability
==========================================================================

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

- Ubuntu 17.10
- Ubuntu 17.04
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

The system could be made to expose sensitive information.

Software Description:
- nvidia-graphics-drivers-384: NVIDIA binary X.Org driver

Details:

Jann Horn discovered that microprocessors utilizing speculative execution
and branch prediction may allow unauthorized memory reads via sidechannel
attacks. This flaw is known as Spectre. A local attacker could use this to
expose sensitive information, including kernel memory.

This update provides mitigations to address the issue, along with
compatibility fixes for the corresponding Linux kernel updates.

Update instructions:

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

Ubuntu 17.10:
  nvidia-384                      384.111-0ubuntu0.17.10.1

Ubuntu 17.04:
  nvidia-384                      384.111-0ubuntu0.17.04.1

Ubuntu 16.04 LTS:
  nvidia-384                      384.111-0ubuntu0.16.04.1

Ubuntu 14.04 LTS:
  nvidia-384                      384.111-0ubuntu0.14.04.1

After a standard system update you need to reboot your computer to make
all the necessary changes.
