Apple Releases 31 Security Fixes

Agram writes, "This week Apple has released fixes for 31 vulnerabilities in its OS, although reportedly a number of known flaws remain un-addressed (according to the instigator of the Month of Kernel Bugs, 'Apple hasn't fixed any of the bugs published during [MoKB], except for the AirPort issue'). Earlier this year, in a move reminiscent of Microsoft's past patching faux pas, Apple released a 'fix' the installation of which broke features unrelated to the targeted flaw. With the growing number of low-level flaws, one has to wonder if Apple's 'more secure' argument still stands. Earlier this month, Microsoft released 6 fixes. Linux does not seem to fare much better. Despite all of these fixes, exploits remain in the wild for each platform. Perhaps, security-wise, the OS choice really boils down to a 'pick-your-poison X user-base' equation?"

They should. But there are two huge problems that make Windows worlds worse than anything else, and will continue to do so until they're actually fixed... Until then, comparing Windows to OS X in desktop* security is merely FUD.

    I. ActiveX. ActiveX is DESIGNED to give a web server full control over your machine. With Flash or Java, even if they're enabled a website can only do stuff if they also exploit a - very rare - flaw in your Virtual Machine. In ActiveX, if you let that control run it can basically do anything. They have some checks to try to block the probably-worst applets, but in the end it runs the code unprotected. Until ActiveX is limited to a VM, it should be totally disabled.

    I'd personally guess that this alone accounts for more regular attacks than everything-else-put-together. Don't use ActiveX. And if you're not using ActiveX, there's little reason to use IE...

    II. Administrator use is chronic. Basically nobody runs OSX in root or sudo-d mode. LOTS of people run Windows routinely in Administrator mode, for a few main reasons: 1) Lots of software only runs that way, and switching is a pain. NO user app should need to be root to run. 2) LOTS of software is very hard to install so a nonAdmin can use it properly, for starters because it only works on the account it was installed into.

    I will completely admit that if all the ISVs behaved perfectly 1 & 2 wouldn't be a problem - but it is VERY plausible for Microsoft to exert enough control to make this better for the vast majority of users. Also, I don't believe all these ISVs do it just to be stupid - my guess is that the structure of Windows makes it MUCH easier to do it that way.

      3) Lots of software that shouldn't even need admin privs to install does for no good reason. (I presume because of the way DLLs and the registry work they need to modify system folders even if they're only going to run as a local user - but that's definitely a Windows problem that it's structured that way.) And once you give those pieces of software admin privs, they can do anything - like installing themself as System so you can't kill them even WITH admin privs. All software should be installable with the MINIMUM possible privs. (Obviously system software or a virus checker needs admin privs.)

    There are plenty of smaller reasons to be unhappy with Windows security, and I'm not trying to say I love their track record. I didn't address at all the fact that it comes out of the box extremely remote exploitable, (average of ~20 minutes for an unpatched box to be exploited on the internet - and several hours to download the patches!) But those are problems other OSes at least sometimes have and you can make reasonable comparisons. Until the two above are fixed, you shouldn't even COMPARE Windows desktop* security to OS X or Linux.

    *Note that I said desktop. While there are some problems, neither of the above super-problems is a server problems.
