Microsoft has shipped an emergency security update to address a zero-day vulnerability. The flaw affects the Windows Print Spooler service and can permit remote threat actors to run arbitrary code and take over vulnerable systems. Microsoft has even taken the unusual step of issuing the fix for Windows 7, which officially reached the end of support as of January 2020. The update does not include Windows 10 version 1607, Windows Server 2012, or Windows Server 2016, for which the Redmond-based company stated patches will be released in coming days.
