This update resolves a newly-discovered vulnerability.

If a user is logged on with administrative user rights, an attacker who
successfully exploited this vulnerability could take complete control of an
affected system. An attacker could then install programs; view, change, or
delete data; or create new accounts with full user rights. Users whose
accounts are configured to have fewer user rights on the system could be l
ess impacted than users who operate with administrative user rights.
