Ubuntu Security Notice USN-3292-1
May 17, 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 crash or run programs as an administrator.

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

Details:

Jason Donenfeld discovered a heap overflow in the MACsec module in the
Linux kernel. An attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code.

Update instructions:

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

Ubuntu 16.10:
linux-image-4.8.0-1036-raspi2 4.8.0-1036.39
linux-image-4.8.0-52-generic 4.8.0-52.55
linux-image-4.8.0-52-generic-lpae 4.8.0-52.55
linux-image-4.8.0-52-lowlatency 4.8.0-52.55
linux-image-4.8.0-52-powerpc-e500mc 4.8.0-52.55
linux-image-4.8.0-52-powerpc-smp 4.8.0-52.55
linux-image-4.8.0-52-powerpc64-emb 4.8.0-52.55
linux-image-generic 4.8.0.52.64
linux-image-generic-lpae 4.8.0.52.64
linux-image-lowlatency 4.8.0.52.64
linux-image-powerpc-e500mc 4.8.0.52.64
linux-image-powerpc-smp 4.8.0.52.64
linux-image-powerpc64-emb 4.8.0.52.64
linux-image-raspi2 4.8.0.1036.40

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.
