Ubuntu Security Notice USN-3404-1
August 28, 2017

linux, linux-raspi2 vulnerability

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

- Ubuntu 17.04


The system could be made to crash under certain conditions.

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


A reference count bug was discovered in the Linux kernel ipx protocol
stack. A local attacker could exploit this flaw to cause a denial of
service or possibly other unspecified problems.

Update instructions:

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

Ubuntu 17.04:
  linux-image-4.10.0-1016-raspi2  4.10.0-1016.19
  linux-image-4.10.0-33-generic   4.10.0-33.37
  linux-image-4.10.0-33-generic-lpae  4.10.0-33.37
  linux-image-4.10.0-33-lowlatency  4.10.0-33.37

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.
