Re: Re: Gadu-Gadu Local/Remote Buffer Overflow vulnerability

Hi JD,

1. It was fully tested on Windows XP SP2 (lang: polish) with all patches, I'm going to test it on other systems. DEP 
wasn't turned on, I suppose this hack might not work with the DEP protection. This issue is exploitable on both both 
privileged/unprivileged user.

2. I did it because of a few reasons. Firstly, the user doesn't have to replace any file, it's enought to place it in a 
new directory in \Gadu-Gadu\emots\ ;> Of course not everyone can do it.
It is a local buffer overflow indeed, but I think that emots.txt files are supposed to be harmless by the GG users. 
What is more, there is a number of people downloading new sets of emoticons, and a great part of them don't check the 
configuration file contents. IMO a nasty exploit would spread pretty easily, after all.

3. What do you mean by asking "how much bytes can you parse"?
