April Patch Tuesday fixes two zero-days, including one under active attack

Microsoft's April Patch Tuesday addresses 167 security vulnerabilities, including two zero-day flaws, one of which is currently being exploited by attackers¹. This extensive update underscores the need for comprehensive patch management, as the vulnerabilities affect a broad range of systems, from servers and endpoints to network devices, browsers, and mobile devices. The fact that one of the zero-day vulnerabilities is under active attack emphasizes the urgency of applying these patches, as delaying could leave systems exposed to malicious activity. By definition, a zero-day vulnerability is a previously unknown flaw in software, and in this case, Microsoft has moved to remediate these issues before further exploitation can occur. This matters to security practitioners because the window for patching is already closing, making it essential to assess their exposure and apply the necessary updates immediately.
