Denial-of-service bug in server component

It appears that our server has a denial-of-service type issue insofar it appears that bogus memory allocation sizes of 24 GB can be triggered which reliably crash the process:

Feb 19 10:02:52 metadaten server[101991]: memory allocation of 24000000000 bytes failed
Feb 19 10:02:53 metadaten systemd[1]: server.service: Main process exited, code=killed, status=6/ABRT
