I would be more satisfied if they gave a proper explanation of what these could have lead to rather than being "well maybe 0.001% chance to exploit this". They did vaguely go over how "two" exploits managed to drop a file, but how impactful is that? Dropping a file in abcd with custom contents in some folder relative to the user profile is not that impactful other than corrupting data or poisoning cache, injecting some javascript. Now reading session data from other sites, that I would find interesting.
