Ancient Flaws May Leave Mac OS X Vulnerable
mdeb writes "ZDNet Australia is running a story that claims Mac OS X 'contains unpatched security flaws of a type that were fixed on alternative operating systems more than a decade ago.' As an example, in August of last year, Apple patched the 'dsidentity' bug, which could easily have been exploited to grant a non-privileged user with admin rights the capability to create and remove 'root' user accounts."
Wow, stop the presses. Security flaws on a *nix based system. Boy that's news no one expected. Or does somehow the magic Apple logo protect you from all harm - and Bill Gates?
"It's the height of ridiculousness to say for those 9 lines you get hundreds of millions."
Now we will just have to sit and wait for Steve Gibson's assessment that Apple intentionally left these exploits open as a backdoor to the system!
was an "alternative" operating system. Why is a hole which was patched 6 months ago news? No harm, no foul.

I watched C-beams glitter in the dark near the Tannhauser gate.
Thank God people have almost cracked running Windows XP on these new Mactels!
Good thing I use Windows ME.
So Neil Archibald, senior security researcher at software security specialists Suresec, says so, and futher said his opinion is justified because Apple does not use software auditing tools to scan enough of its software. This same Suresec, as can be seen on their web page, sells tools and consulting around source code auditing.
It must have happened when they translated the binary off of the stone tablets, likely because they were limited to only bronze tools.
If brevity is the soul of wit, then how does one explain Twitter?
That's the first time I've heard operating systems other than OSX described as "alternative".

We need a mod category for "baiting the untold OSX masses".
I wonder if Suresec/ Neil Archibald pitched their services to Apple and got turned down?
Also, from TFA:
"In my experience -- which is also the experience of some of my peers -- Apple has been very slow to respond to reported security vulnerabilities. It expects security researchers to wait indefinitely to release the vulnerabilities and offers no incentive for them to do so," said Archibald.
So he's trying to make a living on discovering security holes and getting paid not to make them public? I'm okay with this practice, I suppose, but I get the feeling that he's trying to up the ante by generating some bad press for Apple. The whole things seems awful contrived.

Considering the user must be priviliged is it safe to say that the user has already authenticated and in the system. I always use passwords like "asldkfje983r0u!56@#987$%^rnYA(*U()*U&0u" for standard users. If they can crack that they deserve to gain admin rights too. You should see my admin key: it is a 10^12 digit mersenne prime.
Of course, you might have actually read that part and part of your subconscious dismissed it as false. Reminds me of this post from yesterday.
The awkward wording hides the actual meaning. The problem is that a non-priviledged user could *acquire* admin rights and *then* misbehave.
Hey, it doesn't matter and mac os X is uber secure.
now that you've gone and said that, i went and tested it... WITH A GUEST ACCOUNT. and suprise! doesn't work.
I think the article makes a good point and one that Apple needs to address. I've long had the impression that Apple does not do enough security auditing, especially of some of their inherited code and that some of their new software has not been as security minded as it could be. I've not heard any of the grumbling the author has about security researchers being treated poorly or response times being particularly slow, but he may be closer to such things than I.
That said, from the article it is unclear if any of the discovered bugs are remotely exploitable. The one concrete example given is just a local privilege escalation, which is not really all that serious. I do wish that Apple would pay more attention to security and I hope they have a team of elite hackers with their ears on IRC and their hours spent trying to hack boxes. I'm not sure that they do though. My suspicion is a lot of the security comes from the fact that many of the employees are old school UNIX guys that take it more seriously than management. This is, however, unlikely to really bite Apple given the giant target that is Windows where local privilege escalations like the one described here are so common no one reports on them and I don't think MS even bothers to fix them.
That does it! I'm swiching back to Micorosoft Bob!
There are bigger problems in OSX. Auto-installing Dashboard widgets was stupid, and "Open Safe Files After Downloading" (a silly name for "Open Potentially Unsafe Files After Downloading") is an unnecessary risk only minimally mitigated by adding warning dialogs... but at least you can turn it off.

Thankfully even these are not as easily exploited as Microsoft's poisoned gumbo of IE, Outlook, ActiveX, and Security Zones... but Apple really needs to take a good look at the way they approach the Internet, and quit being so trusting.
you quoted a claim that there is an unsubstantiated, unnamed hole. You really should try critical thought sometime.

He's right that Apple users are complacent about security. What he doesn't metnion is that this is a trend amongst security companies (scream loudly about how vulnerable Apple users are because they aren't buying his company's fucking products).
He's right that Apple is very secretive and sometime extremely slow to address security vulnerabilities. He's wrong that Apple not speaking to him means it isn't interested. Apple just learnt the lesson early that being too open to the press (on any topic) is make yourself a victim of their fickle moods.
He's right that there might be large holes in Apple's OS from earlier NeXT days, but he's sure as fuck wrong when he says it applies to both PPC and Intel architectures. Any crack that relies on memory in the stack being overwritten will not be cross platform.
He's right that there are open vulnerabilities. He's wrong and simply trolling (probably for profit, the fucker) when he doesn't mention that none of them are remote.
When I saw the headlines I thought someone had found Egyptian Hieroglyphs from aliens explaining how to break into OSX.
Guess my definition of Ancient isn't the same as the posters.

You see, you hold a crucifix straight up and down for Vampires; cock it 45 degrees so it sort of looks like the Apple logo, and you'll keep Gates away! But, there's a problem with Balmer, you also need the Firefox logo to ward him off. Sometimes, you need Nerdy, the MS Slayer. She's, yes, it's a woman, the chosen one. I can't say anymore now.
And then it was like... beepbeepbeepbeep, and then, like, half my accounts were gone. And I was like, huh?
They were really good accounts too. And then I had to recreate them and I had to do it fast, and they weren't as good...

I was myself wondering what a non-privileged user with admin rights was. But a few more reads finds that it means that the exploit gives admin rights to non-priveleged users.
Software sucks. Open Source sucks less.
(approx. $600 if you were staying current all along)
I'm currently running Panther (and Jaguar on one Mac), and I'm skipping Tiger unless something comes up that requires Tiger that I actually care about. I got Jaguar, used, for $50, and Panther came on my Mac minis, so I'm good until Leopard comes along.
It wasn't until Firefox hit around 10% we started to see hackers paying attention and start exploiting the MS alternative product.
And when precisely did this happen. When "hackers" exploited Firefox, I mean. Real, live, in-the-wild you-better-watch-out exploits?
Apple's always been a minor player, and back in the '80s and early '90s they had a corresponding share of exploits in the classic no-security Windows-like Mac OS. Being 5% back then didn't keep them from being exploited, being easily exploitable made them exploited.
They have patched literally thousands of bugs and security holes and continue to do so at a pretty steady rate. We don't hear about it
If we didn't hear about it, how do you know about it? Do you have GOLD JULY BOOJUM clearance?
Why... how awful. Or the user could have gone to the command line and typed 'sudo foo' and run anything as root that he wanted, including creating and deleting users or whatever else he wants to do, if he has admin rights.
You could at least have chosen an example that wasn't totally useless on 99.9% of Macs. (Those which allow admins to sudo. Most people aren't dumb enough to explicitly grant admin privs to people they don't want to run as root, either because they know they know what it means and choose not to or because they don't and they don't just randomly check every check-box that comes along.)

Sign #11 of Slashdot overdose: You see the phrase 'moderate Republican' and you wonder if that would be a +1 or a -1.
10) Ten million+ active boxes still "too small a number" to target.
9) Worlds virus writers all work at Valve; have no idea what the hell OS X is.
8) OS X originally scheduled to have virus this year; pushed back till Q2 next year to add Intel support and a Universal Binary.
7) Russian Mafia all actually use Macs, tell underlings to keep macs virus free so they don't have to run virus scanners.
6) Forget buffer overflows; real mechanism viruses use to spread is actually second mouse button.
5) No viruses released for sale on ITMS yet.
4) Actually viruses everywhere but Jobs Reality Distorition Field keeps Mac users thinking they are not there.
3) XCode secretly detects and transforms viruses into RSS readers instead at compile time; explains glut on Macs.
2) Virus writers accientally drug virus into one of several hundred "Untitled Folders" on Desktop, now have no idea where it is.
1) Mac owners just too damn pretty for God to let them get viruses.

The main thing that allows so many Linux distributions to work with low maintenance cost is that they are all based around the same kernel. When a fix is issued to the main kernel tree, it is fixed on all Linux's as they update. So distribution makers aren't pressed to patch it manually themselves. Perhaps OS X's variant of the Mach kernel has strayed too far from the main Unix tree, and suffered a form of seclusion from the goings on of the main tree?

The author shows his true colors in the following statement:
Anytime someone claims that the only reason A is safer than B is that B is used more often, alarm bells should go off. It's never the only reason.
We went through the same thing with Linux vs. Windows, Firefox vs. IE, I've seen people make the claim about Opera vs. Firefox, it was said about Mac vs. Windows long before OSX, etc.
If you think about it, the popularity-as-sole-reason argument boils down to claiming that security by obscurity is enough.
He's ZDnet's designated "Apple hitman." They love him because Apple stories - especially negative Apple stories - generate more page views and discussion than any others, especially on News.com.
I'll grab some examples later, but it's no coincidence that this story is almost pure speculation.
I, together with another guy on the MacNN boards, discovered some of the more serious aspects of the vulnerability pertaining to url types and mounting of remote volumes around two years ago, when a website could quite easily download, mount and execute an applescript or any application on your machine without you seeing it (Apple's response to this was the fact that you have to authenticate any new application the first time it's run these days, something now also in WindowsXP and Vista). We notified Apple and waited. And waited. And waited. Finally, after 3 or 4 months, Apple finally released the patch with the new functionality.
It was an extremely serious vulnerability because it was so easy to exploit and Apple really dragged their feet on that, and on other similar cases.
The guy is spot on with that comment. Apple is really slow in responding to possible exploits.
Uhmmm. The submitter has missed the entire point of that exploit - admin rights aren't required, because the program checks for admin credentials with 'getenv("USER")' - ie "export USER=some_admin" is the exploit.
