Microsoft Ships Critical Security Patches to Address 78 Flaws

In a significant move to enhance the security and stability of its software offerings, Microsoft has shipped critical fixes to address a total of 78 security flaws across its various products. This update includes a set of five zero-day vulnerabilities that have already been actively exploited in the wild, underscoring the importance of timely patching.

What are Zero-Day Vulnerabilities?

Zero-day vulnerabilities refer to previously unknown security flaws that are discovered by hackers and can be exploited without prior knowledge of the vulnerability. These types of attacks are particularly challenging for organizations to defend against, as they often catch users off guard. In this case, five zero-day vulnerabilities have been identified in Microsoft's software lineup.
