Description Huzaifa S. Sidhpurwala 2015-03-30 08:17:53 UTC 
Mozilla developer Bobby Holley reported that windows created to hold privileged UI content retained access to privileged internal methods if later navigated to unprivileged content. If a separate flaw was found that allowed for web content to reference these privileged windows, an attacker could use this reference to navigate them to their own content allowing for as escalation of privilege and arbitrary code execution. On its own, this flaw does not allow for privilege escalation by web content.
