    Multiple vulnerabilities have been discovered in Libav. Please review
      the CVE identifiers referenced below for details.
  
Impact :

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

    There is no known workaround at this time."
