Detail

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

- Ubuntu 14.04 LTS

Summary:

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

Software Description: - linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty

Details:

USN-3220-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS.

Alexander Popov discovered that the N_HDLC line discipline implementation in the Linux kernel contained a double-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges.

Update instructions:

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

Ubuntu 14.04 LTS:
linux-image-4.4.0-66-generic 4.4.0-66.87~14.04.1
linux-image-4.4.0-66-generic-lpae 4.4.0-66.87~14.04.1
linux-image-4.4.0-66-lowlatency 4.4.0-66.87~14.04.1
linux-image-4.4.0-66-powerpc-e500mc 4.4.0-66.87~14.04.1
linux-image-4.4.0-66-powerpc-smp 4.4.0-66.87~14.04.1
linux-image-4.4.0-66-powerpc64-emb 4.4.0-66.87~14.04.1
linux-image-4.4.0-66-powerpc64-smp 4.4.0-66.87~14.04.1
linux-image-generic-lpae-lts-xenial 4.4.0.66.52
linux-image-generic-lts-xenial 4.4.0.66.52
linux-image-lowlatency-lts-xenial 4.4.0.66.52
linux-image-powerpc-e500mc-lts-xenial 4.4.0.66.52
linux-image-powerpc-smp-lts-xenial 4.4.0.66.52
linux-image-powerpc64-emb-lts-xenial 4.4.0.66.52
linux-image-powerpc64-smp-lts-xenial 4.4.0.66.52

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.
