Software Description: - linux: Linux kernel Details: Yevgeny Pats discovered that the session keyring implementation in the Linux kernel did not properly reference count when joining an existing session keyring. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: linux-image-3.13.0-76-generic 3.13.0-76.120 linux-image-3.13.0-76-generic-lpae 3.13.0-76.120 linux-image-3.13.0-76-lowlatency 3.13.0-76.120 linux-image-3.13.0-76-powerpc-e500 3.13.0-76.120 linux-image-3.13.0-76-powerpc-e500mc 3.13.0-76.120 linux-image-3.13.0-76-powerpc-smp 3.13.0-76.120 linux-image-3.13.0-76-powerpc64-emb 3.13.0-76.120 linux-image-3.13.0-76-powerpc64-smp 3.13.0-76.120 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.
