Ubuntu Security Notice USN-3035-3
July 14, 2016

linux-lts-wily vulnerability
==========================================================================

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

- Ubuntu 14.04 LTS

Summary:

The system could be made to crash under certain conditions.

Software Description:
- linux-lts-wily: Linux hardware enablement kernel from Wily for Trusty

Details:

USN-3035-1 fixed vulnerabilities in the Linux kernel for Ubuntu 15.10.
This update provides the corresponding updates for the Linux Hardware
Enablement (HWE) kernel from Ubuntu 15.10 for Ubuntu 14.04 LTS.

Jan Stancek discovered that the Linux kernel's memory manager did not
properly handle moving pages mapped by the asynchronous I/O (AIO) ring
buffer to the other nodes. A local attacker could use this to cause a
denial of service (system crash).

Update instructions:

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

Ubuntu 14.04 LTS:
linux-image-4.2.0-42-generic 4.2.0-42.49~14.04.1
linux-image-4.2.0-42-generic-lpae 4.2.0-42.49~14.04.1
linux-image-4.2.0-42-lowlatency 4.2.0-42.49~14.04.1
linux-image-4.2.0-42-powerpc-e500mc 4.2.0-42.49~14.04.1
linux-image-4.2.0-42-powerpc-smp 4.2.0-42.49~14.04.1
linux-image-4.2.0-42-powerpc64-emb 4.2.0-42.49~14.04.1
linux-image-4.2.0-42-powerpc64-smp 4.2.0-42.49~14.04.1

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.
