I knew I saw that in other CoD games! And Google helped me remember: ._.

 

A] "Attempted to overrun string in call to va()" DoS

----------------------------------------------------

 

va() is a function of the Quake 3 engine used to quickly build strings

using snprintf and a static destination buffer.

If the generated string is longer than the available buffer the server

shows an "Attempted to overrun string in call to va()" error and

terminates.

From Call of Duty 2 (and consequently CoD4) the size of this buffer has

been reduced from the original 32000 bytes to only 1024 causing many

problems to the admins, for which reason I created an unofficial fix

for CoD2 in the far 2006 (http://aluigi.org/patches/cod2vawo.lpatch).

 

So in CoD4 an attacker which has joined the server can exploit this

vulnerability through the sending of a command longer than 1024 bytes

causing the immediate termination of the server.

Happened to me twice two.

 

The cod4va exploit is patched on mw2 though. So it might of been a revision that is causing it..

A small update has been released late yesterday that should provide more information on this error.

Erm, have you moved your MW2 folder by any chance?

That issue is caused by moving your MW2 folder.
