Microsoft’s May 2021 Patch Tuesday updates include fixes for four critical security vulnerabilities.
Microsoft’s May Patch Tuesday release addressed a modest 55 cybersecurity vulnerabilities, including just four critical bugs. It’s the smallest monthly update from the computing giant since 2020, but it does contain a patch for a concerning wormable vulnerability found in the Windows OS.
The good news is that none of the vulnerabilities are being actively exploited in the wild, according to Microsoft, though three are listed as publicly known.
The fixes address security flaws across Microsoft Windows, .NET Core and Visual Studio, Internet Explorer (IE), Microsoft Office, SharePoint Server, Open-Source Software, Hyper-V, Skype for Business and Microsoft Lync, and Exchange Server. Besides the four critical bugs, 50 are rated “important” and one is moderate in severity.

Black Hat Asia A trio of researchers at Palo Alto Networks has detailed vulnerabilities in the JET database engine, and demonstrated how those flaws can be exploited to ultimately execute malicious code on systems running Microsoft’s SQL Server and Internet Information Services web server.
The team also said Microsoft dismissed some of their findings as not worthy of a fix.
In a talk today at Black Hat Asia titled Give Me a SQL Injection, I Shall PWN IIS and SQL Server, the three explained they found the JET engine – for years an underlying tech for Microsoft Access and other products, and still downloadable today – has many vulnerabilities. We ve previously reported on such holes.

Fortune 500 Security Shows Progress and Pitfalls
Fortune 500 companies have improved on email security and vulnerability disclosure programs but struggle in asset management and high-risk services.
A deep dive into the security of Fortune 500 organizations reveals they have improved, albeit slowly and unevenly, with gains made in email security and vulnerability disclosure programs (VDPs) and progress lagging in asset management and high-risk services, researchers report.
Rapid7 s Internet Cyber-Exposure Report aims to highlight critical security issues for the CISO, IT security staff, and internal business partners in an enterprise. Its analysis is broken down into five areas of risk: email security, encryption for public Web applications, version management for Web and email servers, risky protocols unsuitable for the Internet, and the increase in VDPs.
