Description
The vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due to the way Firefox handles messages to the parent process that trigger the 'Click to Play' permission prompt to be shown. A remote attacker can create a specially crafted web page and assign arbitrary permissions instead of 'Click to Play' permission, if the user accepted the permission request.
Remediation
Install updates from vendor's website.
