This month, Microsoft fixes 63 vulnerabilities. 2 of which have been publicly disclosed:

CVE-2018-8414 : This is the "Settings.ms" issue. These files were introduced in Windows 8, and they are used to create shortcuts to specific settings pages. The XML instructions for the link can lead to code execution and the user is not warned before opening the files. This has been widely exploited. For details, see the report by SpecterOps: https://posts.specterops.io/the-tale-of-settingcontent-ms-files-f1ea253e4d39

CVE-2018-8373: Not a lot of details here other than the fact that this is yet another scripting engine memory corruption issue. There have been plenty like it, so exploit writers likely have already a game plan how to write yet another exploit for this problem.
