Description Andrej Nemec 2018-12-18 09:45:51 UTC 
In TCP mode, distcc checks the client IP address against a whitelist, which (iirc) is required but can be set quite loosely. There is of course no guarantee that every user on a permitted client address is friendly.

Once the connection is established the client can reasonably easily manipulate the server into running arbitrary commands.
