Microsoft has issued a fix for a critical bug dubbed PrintNightmare.
It says, hackers are using the bug, accidentally disclosed by researchers.
It can help them “install programs; view, change, or delete data; or create new accounts with full user rights” remotely on all versions of Windows.
It affects the Windows Print Spooler, software that manages printing, controlling the order in which print jobs from computers in an office are put in a queue, for example.
