Microsoft has started rolling out today the May 2020 Patch Tuesday security updates. This month, the company has patched 111 vulnerabilities across 12 different products, from Edge to Windows, and from Visual Studio to the .NET Framework.

This month's Patch Tuesday is the third-largest in Microsoft's history after the company patched 115 bugs in March 2020 and 113 in April 2020.

While Microsoft has patched actively-exploited zero-day vulnerabilities in the past two months, there are no such bugs in this release.

This means that system administrators have time at their disposal to test today's Patch Tuesday for bugs or other issues before deploying the updates to all their systems.

Patches shouldn't be delayed too much because threat actors regularly patch-diff the Microsoft security updates in search of bugs that can be easily exploited.

Among the most severe bugs patched this month that could be weaponized for attacks against users in the future, we list:
