Ubuntu Security Notice USN-3266-2
April 25, 2017

linux-hwe vulnerability
==========================================================================

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

- Ubuntu 16.04 LTS

Summary:

The system could be made to crash under certain conditions.

Software Description:
- linux-hwe: Linux hardware enablement (HWE) kernel

Details:

USN-3266-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.10.
This update provides the corresponding updates for the Linux Hardware
Enablement (HWE) kernel from Ubuntu 16.10 for Ubuntu 16.04 LTS.

Alexander Popov discovered that a race condition existed in the Stream
Control Transmission Protocol (SCTP) implementation in the Linux kernel. 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 16.04 LTS:
linux-image-4.8.0-49-generic 4.8.0-49.52~16.04.1
linux-image-4.8.0-49-generic-lpae 4.8.0-49.52~16.04.1
linux-image-4.8.0-49-lowlatency 4.8.0-49.52~16.04.1
linux-image-generic-hwe-16.04 4.8.0.49.21
linux-image-generic-lpae-hwe-16.04 4.8.0.49.21
linux-image-lowlatency-hwe-16.04 4.8.0.49.21

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.
