From Advisory on July 2018 .NET Framework Updates (.NET blog):

The July 2018 Security and Quality Rollup updates for .NET Framework was released earlier this month.

These reports are specific to applications that initialize a COM component and run with restricted permissions. You can reach out to Microsoft Support to get help.
