Ubuntu Security Notice USN-3313-1
June 06, 2017

linux, linux-raspi2 vulnerability
==========================================================================

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

– Ubuntu 16.10

Summary:

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

Software Description:
– linux: Linux kernel
– linux-raspi2: Linux kernel for Raspberry Pi 2

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 versions:

Ubuntu 16.10:
linux-image-4.8.0-1038-raspi2 4.8.0-1038.41
linux-image-4.8.0-54-generic 4.8.0-54.57
linux-image-4.8.0-54-generic-lpae 4.8.0-54.57
linux-image-4.8.0-54-lowlatency 4.8.0-54.57
linux-image-4.8.0-54-powerpc-e500mc 4.8.0-54.57
linux-image-4.8.0-54-powerpc-smp 4.8.0-54.57
linux-image-4.8.0-54-powerpc64-emb 4.8.0-54.57
linux-image-generic 4.8.0.54.66
linux-image-generic-lpae 4.8.0.54.66
linux-image-lowlatency 4.8.0.54.66
linux-image-powerpc-e500mc 4.8.0.54.66
linux-image-powerpc-smp 4.8.0.54.66
linux-image-powerpc64-emb 4.8.0.54.66
linux-image-raspi2 4.8.0.1038.42

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.
