Well, I was right. The announcement for May’s Patch Tuesday has almost exactly the same wording as last month’s. That’s because neither contains any useful information. No, it’s back to the new Security Update Guide, at least if you want to know what Microsoft wants to do to your computer this month.

According to my analysis of this month’s update information in the SUG, there are fifty distinct bulletins, affecting Flash, Internet Explorer, Edge, .NET, Office, and Windows. A total of fifty-six vulnerabilities are addressed. Fifteen of the vulnerabilities are categorized as Critical.

Today Microsoft also issued three advisories:

• Microsoft Security Advisory 4022345: Identifying and correcting failure of Windows Update client to receive updates
• Microsoft Security Advisory 4021279: Vulnerabilities in .NET Core, ASP.NET Core Could Allow Elevation of Privilege
• Microsoft Security Advisory 4010323: Deprecation of SHA-1 for SSL/TLS Certificates in Microsoft Edge and Internet Explorer 11
