FreeBSD : firefox -- Same-origin-policy violation using Service Workers with plugins (172b22cb-d3f6-11e5-ac9e-485d605f4717)

This script is Copyright (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

The Mozilla Foundation reports :

MFSA 2016-13 Jason Pang of OneSignal reported that service workers
intercept responses to plugin network requests made through the
browser. Plugins which make security decisions based on the content of
network requests can have these decisions subverted if a service
worker forges responses to those requests. For example, a forged
crossdomain.xml could allow a malicious site to violate the
same-origin policy using the Flash plugin.
