A pretty cool quote from John Pescatore, Gartner on third-party patches:
My neighbor is a smart guy, and he designs medical machinery. However, I’m pretty sure I won’t be using his homegrown remedy for bird flu. I’m also really sure I don’t want my kids to think its OK to accept medicine from anywhere they find it. It is not a good idea for enterprises or consumers to get in the habit of accepting patches to software from anywhere other than the vendor of the software. Use the time you’d spend undoing them to pressure software vendors to reduce the time the spend talking about security and increase the time they spend reducing security vulnerabilities before they ship their products.
