Just if someone needs to know...

Win98/NT4 Riched20.dll (which WordPad uses) has a classic buffer
overflow problem with ".rtf"-files.

Crashme.rtf :
{\rtf\AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA}

A malicious document may probably abuse this to execute arbitary
code. WordPad crashes with EIP=41414141.

Someone else do deeper investigation since I don't care to.
