Outbreak Alert

A remote code execution vulnerability exists in Windows OS when the Windows Print Spooler service improperly performs privileged file operations. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Microsoft is encouraging customers to either "Disable the Print Spooler service" or "Disable inbound remote printing through Group Policy".
