Software Description: - linux: Linux kernel - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-gke: Linux kernel for Google Container Engine (GKE) systems - linux-raspi2: Linux kernel for Raspberry Pi 2 - linux-snapdragon: Linux kernel for Snapdragon processors Details: Andrey Konovalov discovered a race condition in the UDP Fragmentation Offload (UFO) code in the Linux kernel. A local attacker could use this to cause a denial of service or execute arbitrary code. (CVE-2017-1000112) Andrey Konovalov discovered a race condition in AF_PACKET socket option handling code in the Linux kernel. A local unprivileged attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2017-1000111) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: linux-image-4.4.0-1026-gke 4.4.0-1026.26 linux-image-4.4.0-1030-aws 4.4.0-1030.39 linux-image-4.4.0-1069-raspi2 4.4.0-1069.77 linux-image-4.4.0-1071-snapdragon 4.4.0-1071.76 linux-image-4.4.0-91-generic 4.4.0-91.114 linux-image-4.4.0-91-generic-lpae 4.4.0-91.114 linux-image-4.4.0-91-lowlatency 4.4.0-91.114 linux-image-4.4.0-91-powerpc-e500mc 4.4.0-91.114 linux-image-4.4.0-91-powerpc-smp 4.4.0-91.114 linux-image-4.4.0-91-powerpc64-emb 4.4.0-91.114 linux-image-4.4.0-91-powerpc64-smp 4.4.0-91.114 linux-image-aws 4.4.0.1030.32 linux-image-generic 4.4.0.91.96 linux-image-generic-lpae 4.4.0.91.96 linux-image-gke 4.4.0.1026.27 linux-image-lowlatency 4.4.0.91.96 linux-image-powerpc-e500mc 4.4.0.91.96 linux-image-powerpc-smp 4.4.0.91.96 linux-image-powerpc64-emb 4.4.0.91.96 linux-image-powerpc64-smp 4.4.0.91.96 linux-image-raspi2 4.4.0.1069.69 linux-image-snapdragon 4.4.0.1071.63 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.
