* Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4
* Mozilla Firefox after 42.0 and Firefox ESR 38.x after 38.4
Attackers can exploit these issues to bypass security restrictions and perform unauthorized actions, obtain sensitive information, bypass same-origin policy restrictions to access data, execute arbitrary script code in the browser of an unsuspecting user in the context of another site, and execute arbitrary code in the context of the affected application. Failed exploit attempts will likely result in denial-of-service conditions.
