Microsoft releases emergency patch for Windows 10 flaw

San Francisco: Microsoft has released a Windows patch for a security vulnerability that enabled attackers to transfer malicious code from one machine to another if they had the vulnerability without the knowledge of the users.

The fix is available as KB4551762, an update for Windows 10, versions 1903 and 1909, and Windows Server 2019, versions 1903 and 1909.

“Customers who have already installed the updates released on March 10, 2020 for the affected operating systems should install KB4551762 to be protected from this vulnerability,” Microsoft said on Thursday.

The bug exists in the latest version of Window’s server message block, known as SMB, which lets Windows communicate with devices, like printers and file servers, on the network and across the internet.
