========================================================================== Ubuntu Security Notice USN-3152-1 December 05, 2016 linux 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 Details: Philip Pettersson discovered a race condition in the af_packet implementation in the Linux kernel. A local unprivileged attacker could use this to cause a denial of service (system crash) or run arbitrary code with administrative privileges. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.10: linux-image-4.8.0-30-generic 4.8.0-30.32 linux-image-4.8.0-30-generic-lpae 4.8.0-30.32 linux-image-4.8.0-30-lowlatency 4.8.0-30.32 linux-image-4.8.0-30-powerpc-e500mc 4.8.0-30.32 linux-image-4.8.0-30-powerpc-smp 4.8.0-30.32 linux-image-4.8.0-30-powerpc64-emb 4.8.0-30.32 linux-image-generic 4.8.0.30.39 linux-image-generic-lpae 4.8.0.30.39 linux-image-lowlatency 4.8.0.30.39 linux-image-powerpc-e500mc 4.8.0.30.39 linux-image-powerpc-smp 4.8.0.30.39 linux-image-powerpc64-emb 4.8.0.30.39 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.
