Description

Mozilla Firefox before 47.0 and Firefox ESR 45.x before 45.2 do not ensure that the user approves the fullscreen and pointerlock settings, which allows remote attackers to cause a denial of service (UI outage), or conduct clickjacking or spoofing attacks, via a crafted web site.

Solution(s)

  • mozilla-firefox-esr-upgrade-45_2
  • mozilla-firefox-upgrade-47_0
