CVE-2017-7770

Name of the Vulnerable Software and Affected Versions Firefox versions prior to 54

Description A mechanism in Firefox for Android allows a malicious site to display a spoofed addressbar when entering fullscreen mode after loading a new tab through JavaScript events. This enables the malicious site to show the location of an arbitrary website instead of the one loaded. Desktop Firefox is unaffected.

Recommendations For versions prior to 54, update to version 54 or later to resolve the issue.
