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.

IBM will do testing as Red Hat will not have access to the new hardware for testing. Setting to OtherQA.
