About the latest three Powerpoint vulnerabilities: exploitable?
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?
