I have finished a little program today, it fixes some bugs in the Q3 engine.
It supports JKA and JK2, all versions so far.
1. the download bug ( a.k.a traversal bug [http://www.securityfocus.com/archive...100/0/threaded
2. the callvote bug (you cannot run commands via callvote)
3. cvar overflow bug, dont allows cvar values over 255 chars
4. disables debug commands
plus its possible to log the whole output of the server console
and its possible to force certian cvars.
