Ubuntu Security Notice USN-3188-1

3rd February, 2017

linux vulnerability

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

• Ubuntu 14.04 LTS

Summary

The system could be made to crash if it received specially crafted network traffic.

Software description

• linux - Linux kernel

Details

Andrey Konovalov discovered that the SCTP implementation in the Linux
kernel improperly handled validation of incoming data. A remote attacker
could use this to cause a denial of service (system crash).

Update instructions

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

Ubuntu 14.04 LTS:

linux-image-powerpc-smp 3.13.0.108.116

linux-image-powerpc-e500mc 3.13.0.108.116

linux-image-3.13.0-108-generic 3.13.0-108.155

linux-image-generic 3.13.0.108.116

linux-image-3.13.0-108-powerpc-e500 3.13.0-108.155

linux-image-powerpc64-emb 3.13.0.108.116

linux-image-3.13.0-108-generic-lpae 3.13.0-108.155

To update your system, please follow these instructions: http://ift.tt/17VXqjU.

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.
