USN-3313-1: Linux kernel vulnerability

Ubuntu Security Notice USN-3313-1

6th June, 2017

linux, linux-raspi2 vulnerability

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

Summary

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

Software description

Details

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 version:

Ubuntu 16.10:
linux-image-4.8.0-54-generic

4.8.0-54.57
linux-image-powerpc-e500mc 4.8.0.54.66
linux-image-4.8.0-54-powerpc-smp

4.8.0-54.57
linux-image-4.8.0-54-powerpc-e500mc

4.8.0-54.57
linux-image-powerpc-smp 4.8.0.54.66
linux-image-generic 4.8.0.54.66
linux-image-4.8.0-54-generic-lpae

4.8.0-54.57
linux-image-lowlatency 4.8.0.54.66
linux-image-powerpc64-emb 4.8.0.54.66
linux-image-4.8.0-1038-raspi2

4.8.0-1038.41
linux-image-generic-lpae 4.8.0.54.66
linux-image-4.8.0-54-powerpc64-emb

4.8.0-54.57
linux-image-4.8.0-54-lowlatency

4.8.0-54.57
linux-image-raspi2 4.8.0.1038.42

To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.

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.
