Description Siddharth Sharma 2016-04-25 18:47:30 UTC
Security researcher Holger Fuhrmannek reported an issue where the Mozilla Maintenance Service updater on Windows can delete arbitrary files because of its privileged system access. This file deletion can then potentially be used for further privilege escalation. This flaw requires users to execute a locally saved file in order for it to be triggered.

This issue does not affect non-Windows operating systems.
