Apple Patches Massive Holes In OS X
Trailrunner7 writes with this snippet from ThreatPost: "Apple's first Mac OS X security update for 2010 is out, providing cover for at least 12 serious vulnerabilities. The update, rated critical, plugs security holes that could lead to code execution vulnerabilities if a Mac user is tricked into opening audio files or surfing to a rigged Web site." Hit the link for a list of the highlights among these fixes.
Apple's own security update page (http://support.apple.com/kb/HT4004) lists these six, where did Threatpost author get the number 12 from?:

CVE-ID
The Apple commercials have told me that viruses and security holes are only possible in Windows, so I gather they are patching boot camp installs now
I'm afraid your patch provides insufficient coverage.
The only hole I want Apple to fix is the one they put in my wallet.
You just couldn't wait to post that, could you? FYI: every piece of software needs updates, and there is still always one piece of software that will be more secure than the others. I don't know if OSX is more secure than Windows 7, but both of them will continue to receive updates, that fact doesn't make either of them less secure.

You already posted that in the first comment anonymously, and it wasn't funny then either.

Windows 7 can still be targeted by a IE bug that's been in place since IE6. Safari doesn't have zero day bugs *that* old
How would you know? Zero-day means a non-public exploit.
Two bugs were found in their image libraries (arbitrary code execution bugs in TIFF and RAW-DMG). Makes me wonder if they even tested their image libraries at all when they were being written, because that kind of bug can usually be found in an image library by feeding it random data.
Qxe4
Anything posted on some forum, whispers in an irc chat?
Anything new floating around for a Mac running 10.6 that will do an IE and pop the browser/OS from a remote site?
Most still need the user to enter his/her password as a application/codec.
Mac are still safe to surf with for now.
Macs have a list of malware and loggers, the pre OS 10 had lots too.
But nothing in the wild to infect just yet with a site visit.
If anything existed outside law enforcement, spooks and one off professional solutions, every Mac AV vendor would have a youtube vid up.
A link to buy protection at a fair price after the 2 to 3 mins of safari getting infected after following a link and their product saving the day.
Domestic spying is now "Benign Information Gathering"
No, it can't. Well technically, it can be exploited, but IE runs sandboxed in Win 7 so the exploiter can't really do much.
Yes, it's sarcasm. Deal with it!
But it is.
And patching vulnerabilities that are found just makes it more so.
Sorry, what was your point again?
Saying that OSX is less secure due to these vulnerabilities is how MS said that Linux was less secure than windows. These aren't OS vulnerabilities, they're application vulnerabilities (well, for the programs I recognize as a non-Mac person). The OS itself is fine. The trick is, of course, that some of these things are included practically by default. So as we wouldn't count a problem with notepad as a Windows OS issue, so we shouldn't count ones for other OS's non-essential programs.
/. and a Mac lover, I sincerely doubt you're one of the problem kids for updates on most any system you control.
That's not to say that Mac users have free license to ignore proper security practices. Trojans, poor/shared passwords and not updating their software can leave them as vulnerable, if less targeted, than PC users. Given that one of the problems is with flash (and the fix is as simple as an update), I wonder if there's a good enough of a target out there for hacking Mac WOW players through flash ads hijacks.
Before you flame, I will say that if you're on
"Common sense will be the death of us all"
Has anyone driven a truck thru these gaping holes? Anyone? Beuller? When OSX is suffering from a deluge of viruses from all these supposed gaping holes in it's Architecture, please come back and let us know. Because while every operating system has vulnerabilities, only Microsoft was kind enough to make those vulnerabilities accessible by system wide scripting mechanisms that allowed millions of computer users the world over be the subject of attacks from the hundreds of thousands of pieces of malware constantly fighting to infect Windows PCs. The count (for those who think a security vulnerability makes Apple's points about viruses invalid) is about one hundred thousand to 0. This is being very generous. So, yes, as a matter of fact, there are no viruses for Mac OS X. Not virtually none, not almost none. None.

With default Windows 7 settings, the current exploit doesn't work. IE8 in XP without DEP protection. It CAN theoritically be expolited with DEP but haven't seen any current exploits that work around DEP protection. Also running with non-admin privileges (recommended, and default in vista & windows 7) reduces the attack surface (i.e. backdoors can't be installed without taking advantage of some other vunerability) so the IE vunerability is a bit overblown, following good security practices (which are default in vista & windows 7) already prevent the known attacks.
There aren't enough Windows with IIS installed to make the average script kiddie drool in anticipation in comparison to Linux/BSD with Apache. Oh wait.
If you don;t think the the chance to be the "first person to exploit the 'secure' OS X with a virus" isn;t driving some of these people then you are deluded. Or that genuine organised crime isn't going after the Mac platform (as a non-negligable marketshare) as well as Windows since it is amulti-million dollar industry compromising machines over the net. So far though, not much beyond proof of concept stuff and things that require user credential authentication.
It's no reason to be complacent (and the patching of vulnerabilities is not complacency), or the assertion that OS X is immune to threats, because it isn't. But it has proven to have a pretty good track record - not perfect, but pretty good. Continued work is still needed though.
So as we wouldn't count a problem with notepad as a Windows OS issue, so we shouldn't count ones for other OS's non-essential programs.
Not saying you're in this group, but a lot of people around here have no problem counting IE vulnerabilities against Windows.
So as we wouldn't count a problem with notepad as a Windows OS issue, so we shouldn't count ones for other OS's non-essential programs.
So far as I have seen, problems with user-space components such as Notepad are indeed counted as Windows issues. Which makes perfect sense, since Notepad is present out of the box, and the box says "Windows" on it.
Similarly, OpenBSD has a fork of Apache 1.3 in their base system. If a vulnerability is found in that, then surely it's an OpenBSD vulnerability (hence the difference between base system and ports).
If Apple ships Flash plugin that way, then they have to deal with any security issues that may cause.
I just wonder why the summary title says "MASSIVE holes..." when the original article "serious".. a bit of bias, perhaps??
More realistically, this is just another security update. Find me an OS that doesn't have them, and for similarly "obvious" or "easily found/fixed" (hindsight and armchair hacking being perfect of course) and I'll either switch right away, or dust off the old TRS-80 from my closet to run it on.
The way I see it, if you have a brain and use it while browsing, you are generally fine. But people are stupid. And if you are going to market your product to stupid people, you need to make sure you do everything you can to minimize the damage stupid people can do to others. (Stupid people generally deserve their own damages...)
Now to start the debate over which company is more in the business of marketing to stupid people...
You mean the one with cheaper/slower celeron with less L2 cache, slower DDR2 800 Mhz memory, a cheaper/slower integrated graphics solution, no firewire, a cheaper battery, mono audio speaker, VGA Out Only, no bluetooth standard, no Cam standard, and no optical digital audio output?
Comparable specs?
Yes, my point about IIS vs Apache wasn't that there were more attacks against IIS, just that there are documented and exploited holes.
And yes, there have been many holes found in the various parts of OS X that have been fixed (and some yet to be fixed) but in terms of malware in the wild, there is practically none. There was a disk image that claimed to be Office for Mac on torrent sites that actually ended up deleting your files after you gave it your admin password, and a couple of other proof of concept attacks, but stuff actually out there roaming free in the wild is extremely rare - vanishingly so. I will not say "none" because it is clearly not true, and it allows the possibility of something to emerge, but for all the holes that have appeared in components of OS X, over the course of the life of the OS, no one has demonstrated stuff beyond possibilities.
The TFA does indeed say "could install spyware and delete files" - ie, if the hole is exploited. No one is denying that (and when the hole is closed, they can't) but so far, no one has been able to - the vector for attack has not been there. There was nothing in the wild that exploited some of these holes, and they have been nipped up before anything could be produced.
There are obviously other holes that have yet to be closed - including, as some security people have claimed, ones that have been open and exposed for a very long time (consider the guy who knew of two vulnerabilities and kept one to himself so he could exploit it the next year at the 'break OS X contest'). If that hole was known and vulnerable for a year, where are the in-the0wild exploits actually installing malicious software and keyloggers and so on? The hole was there for a malicious mp4 file, but the malware that exploited it was not.
I'm not not nieve enough to assume or assert that OS X gets a free pass on security, but the prior performance has been good compared to Windows, even with the difference in install base. It's in a similar position to Linux with regard to security holes (and shares holes with some BSD components that the OSS community is also exposed to).
Well, except get access to the authentication credentials for my Internet banking site and transfer all of my money to a numbered Swiss account as soon as I log in. Good thing it can't get at my Freecell high scores though...

The pwn2own contest would say otherwise. Mac is usually the first to go down.
Because for pwn2own you need a zero-day exploit - how high are the chances to find a 0day for Windows and nobody else having it out in the wild until that one day in the year of pwn2own? OTOH, Charlie Miller was sitting on his last winner for over a year, and nobody else found that exploit during that year.

To the guy who modded me down from perfect to terrible Karma - Apple haters still suck
Not at all. Your only looking at the end result as evaluating risk from that, and not the vector of infection.
The flash update wasn't 'dismissed' and I noted it was a serious issue, but the fault lies with Flash. It is an abomination.
The MP4 vulnerability would require someone actually get their hands on a specifically crafted MP4. The typical user either creates their own MP4's from their own audio CD's, or downloads them from iTunes on a Mac. If they are getting them from seedy sources, then they pretty much get what they deserve
The last one I wouldn't consider a huge risk simply for the fact that I had never heard of the format. It would require someone that works with raw image data who happens to get an Adobe DNG image that has this vulnerability. This isn't like some drive by hijacking. I don't see this as a likely path to infection.
What you are linking to is NOT a virus, but a malware that user has to download, authenticate themselves as someone allowed to install software and install it.
If you have a user willing to do that, then all bets are off.
The original assertion still stands though. No viruses (i.e. self propagating code that spreads from machine to machine without user intervention). There aren't any for OS X and I'm not aware of any for Linux/BSD etc either.
As the island of our knowledge grows, so does the shore of our ignorance.
That's how most MP4s come into existence. But an MP4 (or a TIFF for that matter) can be put up onto a webpage by an attacker, and rendered by the browser without the user needing to explicitly download and run it. If visiting a maliciously-crafted website can lead to arbitrary code execution, I'd say there's a serious problem. (I haven't investigated the particular flaws closely enough to tell if that is the case. However, based on the advisory, it seems quite likely.)
