Vulnerability Summary

It exists that the aufs file system in the Linux kernel did not properly maintain POSIX ACL xattr data, when mounted with the non-default allow_userns option. A local attacker could possibly use this to gain elevated privileges. (CVE-2016-2854) 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.
