The Mozilla Maintenance Service can be invoked by an unprivileged user to
read 32 bytes of any arbitrary file on the local system by convincing the
service that it is reading a status file provided by the Mozilla Windows
Updater. The Mozilla Maintenance Service executes with privileged access,
bypassing system protections against unprivileged users. Note: This attack
requires local system access and only affects Windows. Other operating
systems are not affected. This vulnerability affects Firefox ESR < 52.2 and
Firefox < 54.
