    Multiple vulnerabilities have been discovered in libvpx. Please review

Impact :

    A remote attacker could entice a user to open a specially crafted media
      file, possibly resulting in the execution of arbitrary code with the
      privileges of the user running the application, or a Denial of Service.
  
Workaround :
