The Mozilla Windows updater modifies some files to be updated by reading
the original file and applying changes to it. The location of the original
file can be altered by a malicious user by passing a special path to the
callback parameter through the Mozilla Maintenance Service, allowing the
manipulation of files in the installation directory and privilege
escalation by manipulating the Mozilla Maintenance Service, which has
privileged access. 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.
