Issue(s) Resolved in this Hotfix

1. This security fix is designed to enhance security with published applications by making their names harder to predict. To achieve this, the fix appends a token to the Application Name when the application is published. The token is a circumflex followed by a random combination of eight characters/digits. For example, if you publish Microsoft Word with an Application Name of "MS Word" and a Display Name of "Word," users see "Word" when enumerating the application, and an .ica file lists the application as #"MS Word^XXXXXXXX." No changes are made to the application's Display Name (the name of the application as it appears in client interfaces) except for Program Neighborhood custom connections, where the Display Name is equal to the Application Name as it appears in the application's Properties page in the console.

   Important Notes:

   • You must install this fix on all servers in the farm.
   • Application names that contain special characters must be enclosed within quotation marks when using a command line to launch the application, for example, "MS Word^XXXXXXXX."
   • Only the Application Names of applications you publish after you install this fix are changed as described.
   • The Application Names of applications already published when you install this fix are not modified. To update previously published applications within the farm, run dscheck / secureapp.
   • Modifying previously published applications by running dscheck / secureapp can create backward compatibility issues with older .ica files that do not contain the updated Application Name. To prevent such compatibility issues, you can choose to:
     • Not update previously published applications
     • Selectively revert the Application Name to the previous format by deleting the token from the updated Application Name in the application’s Properties page.
   For more information, see Knowledge Center article CTX115245.
