Patch Tuesday Analysis for May 2009

MS09-17 patches something like 14 vulnerabilities in most versions of PowerPoint. Ongoing attacks already exploit at least one vulnerability and more exploit code is on the radar. I disagree with Microsoft's rating of Important for some versions of PowerPoint. Their justification is apparently that the user is required to Open, Save, or Cancel before opening a the malformed document. Well, experience has shown that a user cannot be relied upon to make the wise decision when presented with these options. Therefore apply this patch after minimal testing.

"I liked your high level overview of patches in the table. There are so many sources of patch information which can be very specific or surrounded by other stuff that it’s refreshing to get everything summarised like this. The “Randy’s Recommendation” comment is useful starting point too. Please keep up the good work."
