Ubuntu Security Notice USN-3908-1
March 12, 2019

linux vulnerability
==========================================================================

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

- Ubuntu 14.04 LTS

Summary:

The system could be made to run programs as an administrator.

Software Description:
- linux: Linux kernel

Details:

Jann Horn discovered a race condition in the fork() system call in the
Linux kernel. A local attacker could use this to gain access to services
that cache authorizations.

Update instructions:

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

Ubuntu 14.04 LTS:
  linux-image-3.13.0-166-generic  3.13.0-166.216
  linux-image-3.13.0-166-generic-lpae  3.13.0-166.216
  linux-image-3.13.0-166-lowlatency  3.13.0-166.216
  linux-image-3.13.0-166-powerpc-e500  3.13.0-166.216
  linux-image-3.13.0-166-powerpc-e500mc  3.13.0-166.216
  linux-image-3.13.0-166-powerpc-smp  3.13.0-166.216
  linux-image-3.13.0-166-powerpc64-emb  3.13.0-166.216
  linux-image-3.13.0-166-powerpc64-smp  3.13.0-166.216
  linux-image-generic             3.13.0.166.177
  linux-image-generic-lpae        3.13.0.166.177
  linux-image-lowlatency          3.13.0.166.177
  linux-image-powerpc-e500        3.13.0.166.177
  linux-image-powerpc-e500mc      3.13.0.166.177
  linux-image-powerpc-smp         3.13.0.166.177
  linux-image-powerpc64-emb       3.13.0.166.177
  linux-image-powerpc64-smp       3.13.0.166.177
  linux-image-virtual             3.13.0.166.177

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

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
