Description Tomas Hoger 2022-02-10 18:44:39 UTC 
A Time-of-Check Time-of-Use bug existed in the Maintenance (Updater) Service that could be abused to grant Users write access to an arbitrary directory. This could have been used to escalate to SYSTEM access.

*This bug only affects Firefox on Windows. Other operating systems are unaffected.*
