NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

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.
