========================================================================== Ubuntu Security Notice USN-3188-1 February 03, 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 versions: Ubuntu 14.04 LTS: linux-image-3.13.0-108-generic 3.13.0-108.155 linux-image-3.13.0-108-generic-lpae 3.13.0-108.155 linux-image-3.13.0-108-lowlatency 3.13.0-108.155 linux-image-3.13.0-108-powerpc-e500 3.13.0-108.155 linux-image-3.13.0-108-powerpc-e500mc 3.13.0-108.155 linux-image-3.13.0-108-powerpc-smp 3.13.0-108.155 linux-image-3.13.0-108-powerpc64-emb 3.13.0-108.155 linux-image-3.13.0-108-powerpc64-smp 3.13.0-108.155 linux-image-generic 3.13.0.108.116 linux-image-generic-lpae 3.13.0.108.116 linux-image-lowlatency 3.13.0.108.116 linux-image-powerpc-e500 3.13.0.108.116 linux-image-powerpc-e500mc 3.13.0.108.116 linux-image-powerpc-smp 3.13.0.108.116 linux-image-powerpc64-emb 3.13.0.108.116 linux-image-powerpc64-smp 3.13.0.108.116 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.
