Well guys, it seems we have some idiots using an exploit to crash our servers. If your server keeps crashing with the error message

ERROR: Info_SetValueForKey: oversize infostring

then your server is being attacked as well.

IP of that idiot: 84.149.231.52 (p5495E734.dip.t-dialin.net)

What can you do?

Wait until id software releases a new point release or download and apply this fix.

Or block them with a firewall:
iptables -I INPUT 1 -p udp -m mport --dports 27960 -m string --string "\xff\xff\xff\xffgetstatus" -m length --length 50:inf -j DROP
iptables -I INPUT 1 -p udp -m mport --dports 27960 -m string --string "\xff\xff\xff\xffgetinfo" -m length --length 50:inf -j DROP

He can crash servers with an old school packet dump...similiar to crashing/booting yahoo, msn, & other chat clients but on a larger scale.

Send enough packets and you can crash a network or even restart the victims' computer. Winking

Purest evil... :twisted:

I used neotrace of this IP, located in Nürnberg.
