Ah, you are using the Host_Error:Sv_ParseVoiceData bug

[DruGzOG]

yup, it's an exploit.

Host_Error:Sv_ParseVoiceData

Yes, this exploit uses this error, for the first time it has been noticed in 2002.

Maybe you don't understand, I just started the server. In a sense it may be an exploit. How many people know this? 1? 2?

Sad, but in Russia very many actually. It is posted on every cheaters community like removed

YamiKaitou, your server seems to be down already. I cannot connect to it...

Because I stopped it. anakusama did it and I was able to see the error message. Also, do not post sites that provide info on exploits or cheats

This can be patched up using the orpheu module correct?

[retribution]

Whoops sorry for the link.

What module? I used hex-editor on swds.dll and changed some values. But this is temporary solution 'cos exploit can be patched as well. You have better idea?

[anakusama]

Falls because of the data in the second package:
00 00 00 01 00 00 00 00 5B 19 01 01 1B 01 11 41 01 11 41 01 56 04 18 41 04 54 14 04 11 51 41 44 53 41 11 01 41 11 01 01
These are the ciphered data. Actually this message at decoding looks so:
08 44 44 44 44 44 44 44
This line 8 means a type package clc_voicedata (i.e. the vocal data from a hammock).
The subsequent 2 bytes (0x4444) is a length of the vocal data.
And as it is known at value higher 0x1000 the server itself falls (gives out message and stops work).
More shortly, to programmers from VALVE in general laziness if's to write.

-------------------------------
Has experimented patching is sensitive:
In swds.dll it is changed:
8B EC B8 0C 10 00 00
On
8B EC B8 0C 50 00 00
And also:
3D 00 10 00 00 89 45
On
3D 00 50 00 00 89 45
After this operation server does not fall.
But as it is easily possible patching exploit, having replaced 0x4444 on 0x7FFE (and it will bring down yours servers and further).
And it is possible to be engaged in more "abrupt" patching: to add additional Check for the length and as it is possible to add a cycle of reading of the buffer recv.
