Hi,

I was trying to confirm that, but under Windows XP MCE (lang: German and 
English) with all patches, overflows on other address. Can anybody confirm 
that?


I've tested it on VPC with Windows XP SP2 PL and I can confirm it
works as the author stated.



I agree with JohnDo, why just don't send user a specially crafted 
kernel32.dll :).

I don't. First, it's a .txt file, not a .dll file. Second, this file
is a part of emoticon sets. You do not expect emoticons to execute
some code do you ? ;>




2. Why did you wrote VERY HIGH threat? This is local buffer overflow. 
Moreover user has to
replace original file. This vulnerability has more to do with SE :(.

As far as I know the user does not have to overwrite any file. See
http://vexillium.org for a video of exploitation without replacing any
files. "Very High" might be a little to much, but just a little imho

Best Regards ;>
