About the latest three Powerpoint vulnerabilities: exploitable? Jul 18 2006 01:02PM

We have analyzed the three proof-of-concept documents recently posted on the mailing list, and they don't appear exploitable to us. Specifically:

- powerpnt.exe: NULL pointer dereference, unusable. Are we missing anything?

- memory corruption: we apparently control the address, but not the contents written to it. Doesn't appear usable

- mso.dll: this didn't work for us. We see an integer overflow exception being raised with RaiseException, followed by a C++ exception, but no apparent side effects. PowerPoint complains, but closes cleanly and works fine thereafter

Is any of the three supposed to go beyond a local DoS? anyone else has analyzed them?
