MS Security Guy Wants Vista Bugs Rated Down

jcatcw writes "Gregg Keizer reports that Michael Howard, an MS senior security program manager, says that the Microsoft Security Response Center (MSRC) is being too conservative in its Vista vulnerability rating plans. Microsoft's own bug hunters should cut Windows Vista some slack and rate its vulnerabilities differently because of the operating system's new, baked-in defenses."

If you've read Michael Howard's writings, he's certainly not a "narrow minded fool". On his blog, he talked about security features in the compiler and linker such as /GS and /SafeSEH. With these in place--and OS-based onese, such as Address Space Layout Randomization and Data Execution Prevention-- buffer overflows still exist, but are much harder to effectively exploit. Yes, the process will abort, so you could still have a denial of service attack, but you've greatly reduced the chance of a more serious remote code execution.

Note that OpenBSD is also adopting similar defense-in-depth strategies, including SSP and N^X. Adoption is much more haphazard on Linux Distros, so you may be at much more risk running an application such as SSH on Linux than on OpenBSD even when it is compiled from the same source code.
