Ubuntu Security Notice USN-3219-1
March 07, 2017

linux vulnerability
==========================================================================

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: Linux kernel

Details:

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-3.13.0-112-generic 3.13.0-112.159
linux-image-3.13.0-112-generic-lpae 3.13.0-112.159
linux-image-3.13.0-112-lowlatency 3.13.0-112.159
linux-image-3.13.0-112-powerpc-e500 3.13.0-112.159
linux-image-3.13.0-112-powerpc-e500mc 3.13.0-112.159
linux-image-3.13.0-112-powerpc-smp 3.13.0-112.159
linux-image-3.13.0-112-powerpc64-emb 3.13.0-112.159
linux-image-3.13.0-112-powerpc64-smp 3.13.0-112.159
linux-image-generic 3.13.0.112.120
linux-image-generic-lpae 3.13.0.112.120
linux-image-lowlatency 3.13.0.112.120
linux-image-powerpc-e500 3.13.0.112.120
linux-image-powerpc-e500mc 3.13.0.112.120
linux-image-powerpc-smp 3.13.0.112.120
linux-image-powerpc64-emb 3.13.0.112.120
linux-image-powerpc64-smp 3.13.0.112.120

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.
