Ubuntu Security Notice USN-3249-2
March 30, 2017

linux-lts-xenial vulnerability
==========================================================================

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

- Ubuntu 14.04 LTS

Summary:

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

Software Description:
- linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty

Details:

USN-3249-1 fixed a vulnerability in the Linux kernel for Ubuntu 16.04
LTS. This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu
14.04 LTS.

It was discovered that the xfrm framework for transforming packets in the
Linux kernel did not properly validate data received from user space. A
local attacker could use this to cause a denial of service (system crash)
or execute arbitrary code with administrative privileges.

Update instructions:

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

Ubuntu 14.04 LTS:
linux-image-4.4.0-71-generic 4.4.0-71.92~14.04.1
linux-image-4.4.0-71-generic-lpae 4.4.0-71.92~14.04.1
linux-image-4.4.0-71-lowlatency 4.4.0-71.92~14.04.1
linux-image-4.4.0-71-powerpc-e500mc 4.4.0-71.92~14.04.1
linux-image-4.4.0-71-powerpc-smp 4.4.0-71.92~14.04.1
linux-image-4.4.0-71-powerpc64-smp 4.4.0-71.92~14.04.1
linux-image-generic-lpae-lts-xenial 4.4.0.71.58
linux-image-generic-lts-xenial 4.4.0.71.58
linux-image-lowlatency-lts-xenial 4.4.0.71.58
linux-image-powerpc-e500mc-lts-xenial 4.4.0.71.58
linux-image-powerpc-smp-lts-xenial 4.4.0.71.58
linux-image-powerpc64-smp-lts-xenial 4.4.0.71.58

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.
