A federal cybersecurity agency this week advised users and administrators to update Microsoft Windows due to “multiple vulnerabilities” that can allow “an attacker can exploit some of these vulnerabilities to take control of an affected system.”

The Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency wrote on March 14 that it “encourages users and administrators to review Microsoft’s March 2023 Security Update Guide” for necessary updates. Microsoft’s patch, issued Tuesday, was rolled out to deal with about 80 security flaws in the Windows operating system, two of which are being actively exploited.
