Ubuntu Security Notice USN-3313-2
June 07, 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 run programs as an administrator.

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

Details:

USN-3313-1 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.

It was discovered that a buffer overflow existed in the trace subsystem in
the Linux kernel. A privileged local attacker could use this to execute
arbitrary code.

Update instructions:

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

Ubuntu 16.04 LTS:
linux-image-4.8.0-54-generic 4.8.0-54.57~16.04.1
linux-image-4.8.0-54-generic-lpae 4.8.0-54.57~16.04.1
linux-image-4.8.0-54-lowlatency 4.8.0-54.57~16.04.1
linux-image-generic-hwe-16.04 4.8.0.54.25
linux-image-generic-lpae-hwe-16.04 4.8.0.54.25
linux-image-lowlatency-hwe-16.04 4.8.0.54.25

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.
