My 7 line python fuzzer found several file format bugs in 3 hours. Quite
alarming.
No deep analysis was done, I leave that to the community.
These are some of the results:
file789-1.doc - Unspecified Overflow in word 2007 - Crash in wwlib.dll .
Code execution is not trivial.
file798-1.doc . Word 2007 CPU exhaustion DOS - CPU shoots up to 100 %.
file613-1.doc - Word 2007 CPU exhaustion DOS + ding - CPU shoots up to
100 %, and windows goes .ding!.
evil.hlp . Heap overflow in Windows HLP files - Funky heap overflow crash,
more than meets the eye (does this sound familiar to anyone?)
These files can be found at

Be safe,
