MS Virtual PC Flaw Defeats Windows Defenses

Coop's Troops writes "An exploit writer at Core Security Technologies has discovered a serious vulnerability that exposes users of Microsoft's Virtual PC virtualization software to malicious hacker attacks. The vulnerability, which is unpatched, essentially allows an attacker to bypass several major security mitigations — DEP, SafeSEH and ASLR — to exploit the Windows operating system. As a result, some applications with bugs that are not exploitable when running in a not-virtualized operating system are rendered exploitable if running within a guest OS in Virtual PC."

So how many months do you need to review once you are told about it?

Simple. How many months will you give them before you go public?

At the possibility of being flamebait here, how the heck does MS keep publishing products full of security holes? I know Linux and Mac have had their share of holes, but it seems as if every week there's a new announcement about some MS product that has either a 0 day flaw, or another MAJOR flaw? And even worse is their failure to deal with them in a reasonable amount of time! I mean 6 months to COMMENT on an advisory? That's ridiculous... Sure, they may have a lot of notices to work through, but if that's the case, hire more developers to deal with the security issues! They are out spreading the message that you can depend on MS products, and then leave gaping holes open for months... Not to long ago (within the month), they delayed a patch --well, wanted to anyway before they were called out on it-- for a 0-day in IE by 3 weeks, so that they could put it in a "planned update to IE"... If this was a popular open source project trying to pull this stuff, how quickly would a fork surface? Then again, it's all about placating the sheeple, right?
