Ubuntu Security Notice USN-2644-1
June 15, 2015

linux-lts-utopic vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS

Summary:

The system could be made to run programs as an administrator.

Software Description:
- linux-lts-utopic: Linux hardware enablement kernel from Utopic

Details:

Philip Pettersson discovered a privilege escalation when using overlayfs
mounts inside of user namespaces. A local user could exploit this flaw to
gain administrative privileges on the system.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 14.04 LTS:
linux-image-3.16.0-41-generic 3.16.0-41.55~14.04.1
linux-image-3.16.0-41-generic-lpae 3.16.0-41.55~14.04.1
linux-image-3.16.0-41-lowlatency 3.16.0-41.55~14.04.1
linux-image-3.16.0-41-powerpc-e500mc 3.16.0-41.55~14.04.1
linux-image-3.16.0-41-powerpc-smp 3.16.0-41.55~14.04.1
linux-image-3.16.0-41-powerpc64-emb 3.16.0-41.55~14.04.1
linux-image-3.16.0-41-powerpc64-smp 3.16.0-41.55~14.04.1

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.
