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:7 relevant fixed versions and status.

The nsDisplayList::HitTest function in Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 mishandles rendering display transformation, which allows remote attackers to execute arbitrary code via a crafted web site that leverages "type confusion."
