Synopsis:    Important: firefox security update
Issue Date:  2011-08-31


Mozilla Firefox is an open source web browser. XULRunner provides the 
XUL Runtime environment for Mozilla Firefox.

It was found that a Certificate Authority (CA) issued a fraudulent HTTPS
certificate. This update renders any HTTPS certificates signed by that
CA as untrusted, except for a select few. The now untrusted certificates
that were issued before July 1, 2011 can be manually re-enabled and used
again at your own risk in Firefox; however, affected certificates issued
after this date cannot be re-enabled or used.

All Firefox users should upgrade to these updated packages, which 
contain a backported patch. After installing the update, Firefox must be 
restarted for the changes to take effect.
