MacOS - ROP Mitigation Firefox plugin-container

Hi,

 

I reported the following problem in a case:

 When an  user visits Hotmail or Gmail with Firefox, user gets ROP mittigation notification. This does not happen with Safari or Chrome.

Mac with 10.10.5

We use ESM 4..0.0.24417 with content update 15-1078

 

ROP chain utilization attempt detected

 

And support came back with this answer:

 

It  has been confirmed to be a FP, here is how you can stop getting this event again.

Create the following policy:

- go to Policies -> Exploit -> Protection Modules, click Add

- select ROP Mitigation , then enter ninja mode - click on Components button and set C0 to OFF

- under Process tab, add plugin-container.exe to the selected processes list.

- name the policy under Name tab and click Apply.

Maybe this can be helpful for you too.

 

Kind regards,

Michael
