By installing an application that has more that 2000 files I have got the famous hash error 0x80091007 on the client (CAS.log). It seems that SCCM has a problem when calculating the hash for a download with too many files. The solution was simply to customize the application so that these 2000 files are downloaded as a single zip file, unzipped on the client and the application is subsequently installed on the client.

In order to exploit this issue a physical access to the computer is required. The computer has to bee rebooted into Intel Management Engine BIOS Extension (MEBx). This is easily done by pressing Ctrl+P when the DELL Logo is displayed by booting. Then there is a big chance that the default password has not been changed (default password is: admin) and the attacker can get into the computer's Intel AMT and set it for remote attack. And indeed I was able to confirm the issue on a dell notebook (Latitude E7450). In order to disable Intel AMT on a dell computer follow the instructions here.
