Software Description: - linux: Linux kernel Details: A stack overflow was discovered in the the microcode loader for the intel x86 platform. A local attacker could exploit this flaw to cause a denial of service (kernel crash) or to potentially execute code with kernel privileges. (CVE-2015-2666) It was discovered that the Linux kernel's IPv6 networking stack has a flaw that allows using route advertisement (RA) messages to set the 'hop_limit' to values that are too low. An unprivileged attacker on a local network could exploit this flaw to cause a denial of service (IPv6 messages dropped). (CVE-2015-2922) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: linux-image-3.13.0-51-generic 3.13.0-51.84 linux-image-3.13.0-51-generic-lpae 3.13.0-51.84 linux-image-3.13.0-51-lowlatency 3.13.0-51.84 linux-image-3.13.0-51-powerpc-e500 3.13.0-51.84 linux-image-3.13.0-51-powerpc-e500mc 3.13.0-51.84 linux-image-3.13.0-51-powerpc-smp 3.13.0-51.84 linux-image-3.13.0-51-powerpc64-emb 3.13.0-51.84 linux-image-3.13.0-51-powerpc64-smp 3.13.0-51.84 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. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.
