Summary

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

Software Description:

- linux-lts-trusty: Linux hardware enablement kernel from Trusty for Precise ESM

Details:

USN-3908-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04

LTS. This update provides the corresponding updates for the Linux

Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu

Update Instructions

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

Ubuntu 12.04 ESM:
  linux-image-3.13.0-166-generic  3.13.0-166.216~precise1
  linux-image-3.13.0-166-generic-lpae  3.13.0-166.216~precise1
  linux-image-3.13.0-166-lowlatency  3.13.0-166.216~precise1
  linux-image-generic-lpae-lts-trusty  3.13.0.166.156
  linux-image-generic-lts-trusty  3.13.0.166.156

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.
