Patch Windows to avoid denial of service attacks: Microsoft

Microsoft has issued an urgent security alert advising customers to apply patches for vulnerabilities in the Windows transmission control/internet protocol (TCP/IP) networking stack, as its security researchers expect the flaws to be exploited soon. Of the three vulnerabilities, the CVE-2021-24086 flaw is easy to exploit for denial of service attacks that cause a STOP error with a Blue Screen of Death in Windows, Microsoft said. Two remote code execution (RCE) bugs are also fixed in this month’s Patch Wednesday set of security updates.
