Critical Updates: 3
Important Updates: 6
Of the 3 critical updates, all three are likely exploitable according to Microsoft. Our recommendation is to install all three patches, one of which is the recent out-of-band patch for the Internet Explorer zero-day. Note: Some of these updates do require a restart.
Some of the vulnerabilities, such as one for Microsoft SharePoint Server, have a more limited scope than those targeting IE, such as the updates that address memory corruption vulnerabilities in Internet Explorer. These are more likely to be exploited and will impact many more devices.
