USN-4199-1 fixed several vulnerabilities in libvpx. This update provides
the corresponding update for Ubuntu 14.04 ESM.
Original advisory details:
It was discovered that libvpx did not properly handle certain malformed
WebM media files. If an application using libvpx opened a specially crafted
WebM file, a remote attacker could cause a denial of service, or possibly
execute arbitrary code.
