Microsoft released the April 2020 Office security updates on April 14, 2020, with a total of 55 security updates and 5 cumulative updates for 7 different products. Microsoft also patched three zero-day vulnerabilities yesterday, with two of them actively exploited in the wild. The RCE bugs allow attackers to execute arbitrary code in the context of the SharePoint app pool and SharePoint server farm account after successfully exploiting Windows devices running unpatched Office products. Earlier this month, Microsoft also published non-security Microsoft Office updates with several crash fixes for Windows Installer editions of Office 2016.
