**PLEASE DO NOT POST A COMMENT IF ITS ABOUT SAFARI IN BETA**
These bugs have been verified in the current PRODUCTION copy on OSX (Safari 2.0.4).
Apple just released a Safari for Windows beta at http://www.apple.com/safari. Using publicly available tools we had a DoS in no time. Keeping with our disclosure policy, we do not report bugs to Apple.
UPDATE: Whoops, sorry, thats not a DoS, its memory corruption.
UPDATE 2: Per Request....WinDBG output of a new bug. These are popping out like hotcakes.
It appears I am not the only person who had this idea today?
UPDATE 4: Thor Larholm has also found a bug.
I'd like to note that we found a total of 6 bugs in an afternoon, 4 DoS and 2 remote code execution bugs. We have weaponized one of those to be reliable and its diffrent that what Thor has found. I can't speak for anybody else but the bugs found in the beta copy of Safari on Windows work on the production copy on OSX as well (same code base for alot of stuff). The exploit is robust mostly thanks to the lack of any kind of adanced security features in OSX, I write about it here.
UPDATE 5: I've been asked what our disclosure policy is. Its pretty simple, in most cases we will give vendors as long as they need to fix problems. If the vendor is unresponsive or make threats, we will give them 30 days then release details. If a vendor answers a vulnerability disclosure with marketing and spin attempts, we no longer report vulnerabilities to that vendor but the information goes into our Hacker Eye View program for customers and will be used in pentesting. We do not sell the vulnerabilities to any 3rd party.
