This fixes the recently discovered security problems.
0.2.8.X and 0.3.0 are affected by:
- A forged client can request too many network object
ID numbers from the client, freezing it
- A clumsy remote administrator can issue commands
that produce too much output, freezing the server
All versions are affected by:
- A forged client can send network objects with wrong
owner information, crashing/terminating the server
The patch for 0.2.6 is yet untested, the current
client can't connect to a 0.2.6 server on the LAN.
