One Patch to Rule Them All
On August 15th, Shane Hird published the details of a potentially serious issue with the Windows XP Help and Support Center where the contents of a known directory could be deleted if an attacker tricked someone into executing a maliciously formatted URL. At the time, there was no published patch, and no official work-around.
For the most part, it went widely unnoticed. Well, that may be a generalization -- I failed to notice it, as did all of the security people I know, but that doesn't mean the bad guys didn't tuck the information away into their cache of "crappy things to do to people when you're a script kiddie."
Granted, it wasn't a huge bug, but it did allow for one to trivially delete files from a victim's box (under the right circumstances). And since we are talking about an exploit primarily against the end user -- the home user -- we could hardly expect that the potential targets would be employing "best practices" security that would mitigate their exposure.
