Ubuntu 16.04 LTS: USN-4228-1 Critical: Kernel Buffer Overflow Issues

The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: linux-image-4.4.0-1064-kvm 4.4.0-1064.71 linux-image-4.4.0-1100-aws 4.4.0-1100.111 linux-image-4.4.0-1127-raspi2 4.4.0-1127.136 linux-image-4.4.0-1131-snapdragon 4.4.0-1131.139 linux-image-4.4.0-171-generic 4.4.0-171.200 linux-image-4.4.0-171-generic-lpae 4.4.0-171.200 linux-image-4.4.0-171-lowlatency 4.4.0-171.200 linux-image-4.4.0-171-powerpc-e500mc 4.4.0-171.200 linux-image-4.4.0-171-powerpc-smp 4.4.0-171.200 linux-image-4.4.0-171-powerpc64-emb 4.4.0-171.200 linux-image-4.4.0-171-powerpc64-smp 4.4.0-171.200 linux-image-aws 4.4.0.1100.104 linux-image-generic 4.4.0.171.179 linux-image-generic-lpae 4.4.0.171.179 linux-image-kvm 4.4.0.1064.64 linux-image-lowlatency 4.4.0.171.179 linux-image-powerpc-e500mc 4.4.0.171.179 linux-image-powerpc-smp 4.4.0.171.179 linux-image-powerpc64-emb 4.4.0.171.179 linux-image-powerpc64-smp 4.4.0.171.179 linux-image-raspi2 4.4.0.1127.127 linux-image-snapdragon 4.4.0.1131.123 linux-image-virtual 4.4.0.171.179 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.
