ZERO-DAY

This is a huge month for Patch Tuesday as Microsoft attempts to address 78 unique vulnerabilities spanning Windows desktop and server platforms, Microsoft Office and core development tools. Without the pressure of a publicly reported vulnerability and no Zero-days to urgently address, we recommend a measure pace of testing before deployment for the Windows and Office updates, with a more rapid pace for the IE and development tools patches.

Windows

This is pretty massive update to the Windows platform with fifteen updates rated as critical and 55 rated as important by Microsoft. The two biggest issues relate to how Microsoft handles fonts (a recurring theme) and the worm-able vulnerability (CVE-2019-1222)  in Microsoft Remote Desktop Services (formerly Terminal Services). Not only does this month’s Patch Tuesday update attempt to address  a large number vulnerabilities, it creates a large testing area for deployment engineers.

Browsers

Microsoft has attempted to address twelve vulnerabilities to both its web browsers (Edge and Internet Explorer) with nine rated as critical. Though we don’t have any vulnerabilities publicly reported or known to be exploited, two groups of issues relate to the Chakra scripting engine and how both browsers handle memory.

This is an interesting month for Office updates. For August we see five patches rated as critical by Microsoft and the remaining nine updates are rated as important. Unusually, Microsoft has released an update to a trusted font issue for Office for Mac, and the venerable Office 2013 has an update to the aging Microsoft JET database engine.
