Barely a few hours after the beta release of the Safari browser for Windows, we've already picked up word of possible security issues. This appears to be the report being mentioned by David Maynor of Errata Security - the guy made famous for demonstrating how to "hack" a MacBook wirelessly. Here reads the consultant's description of the six detected bugs:

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 different 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).

Given that it's a Beta releases, we'll be keeping our eyes peeled in case more developments are announced as Safari goes through its paces.
