Story of a dumb patch
Posted by jericho
Cesar Cerrudo of Argeniss Information Security recently posted announcing the release of a new paper titled “Story of a dumb patch”.
Abstract: This paper is an advisory but mostly it describes a mistake made by Microsoft on patch MS05-018 where Microsoft failed to properly fix a vulnerability having to release a new patch MS05-049. Hopefully this paper will open the eyes to software vendors to not repeat this kind of mistakes.
Conclusion: As you have seen Microsoft did what you never have to do, Microsoft failed to build a good fix thus losing a lot of money and time, also Microsoft make users to lost time (maybe also money if you think time=money) since users have to patch again what they have already patched. I personally have seen Microsoft improvements on all aspects of security over the last years, but I think that Microsoft still needs some fine tunning on the patching process in order to avoid this kind of mistakes. I also must say that Microsoft is 1000% better than Oracle at handling and patching vulnerabilities.
