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

    A remote attacker could entice a user to view a specially crafted web
      page, possibly resulting in the execution of arbitrary code with the
      privileges of the process or a Denial of Service condition. Furthermore,
      a remote attacker may be able to perform Man-in-the-Middle attacks,
      obtain sensitive information, spoof the address bar, conduct clickjacking
      attacks, bypass security restrictions and protection mechanisms, or have
      other unspecified impact.
  
Workaround :

    There is no known workaround at this time."
