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"?
