(InfoWorld) - Apple on Thursday unveiled the year's fifth major security update for Mac OS X to patch 17 vulnerabilities, but fewer than one-third of them could lead to hackers injecting their own code into a compromised system. Thursday's release also marked the first time this year that an operating system security update from Apple did not patch a vulnerability disclosed by the January Month of Apple Bugs project. If Apple sorted bugs by a ranking system -- as do other vendors, including Microsoft Corp. -- most of the bugs fixed by Security Update 2007-005 would be rated less than critical. In eight out of the 17, for example, exploits could do no more damage than to generate a denial of service of, or crash, the affected component. Microsoft typically pegs such vulnerabilities as "important" rather than "critical." Only five of the patched vulnerabilities could result in an attacker executing his own code. Among the serious bugs is one in how Mac OS X 10.4, known as Tiger, handles PDF files. "By enticing a user to open a maliciously crafted PDF file, an attacker could trigger the overflow, which may lead to an unexpected application termination or arbitrary code execution," Apple's advisory said. Attacks sporting this strategy, although rare on Macs, are common threats faced by Windows users, who have had to learn -- sometimes unsuccessfully -- to be wary of unexpected file attachments. Another dangerous flaw fixed Thursday exists in the code that maps ports on home networks in iChat, Apple's instant messaging service and software. An attacker need only send a malformed packet to trigger a buffer overflow, which could then be used to add malicious code to the Mac. The hacker, however, must have access to the local network to exploit the bug. Other parts of Mac OS X that were patched Thursday include BIND (Berkeley Internet Name Domain), the de facto standard Domain Name System server software, which was patched against four vulnerabilities; the Ruby CGI library (two vulnerabilities); and Fetchmail (one vulnerability). Although Thursday's update pushed Apple's year-to-date patch total to over 100, there was a bright side: It included fixes for fewer flaws thanÂ last monthÂ (25) and the month before (45). The security update can be downloaded from theÂ Apple siteÂ or using Mac OS X's built-in update service.

In 1980, I signed a deal with a company to market a product I was developing. The contract required me to turn over the source code, which I did. One day I went to a meeting at the office of the company, and there on the product manager's desk, right next to a door that opened to the outside, was a floppy labeled "Dave Winer's source code" in big letters.  If you own a Mac you may soon find out what that felt like. It's amazing to me that the tech blogosphere doesn't treat Apple's policy re broken hard disks as the huge gaping security hole that it is.  Think about it. We worry about bad people getting their hands on little pieces of data that, when added together, give them the power to be you in banking and credit transactions.  Think about what you would do if your laptop was stolen. Well, if you own a Mac and its hard disk goes bad, and you make the mistake of bringing it to Apple for service, you will turn over all that data to Apple. Not "may" or "might" but "will." What Apple in turn does with that data is none of your affair. They don't sign anything or offer any guarantees that they won't sell the disk to a data miner. Think it can't happen or that it's unlikely? I don't gain much comfort from your feeling of security. I've been writing about this issue since December 22. Usually when I write something critical of Apple, the results are mixed. Some people are supportive, but far more people attack. This time the ratio is very different. Almost everyone who has commented gets that there's a huge problem here. Can we solve this problem? Of course we can.  Some say that other vendors do this too. That gives me less comfort, not more. That means there's no escaping this crazy way of treating user's confidentiality. Ultimately it hurts the vendors because people can't use their computers for things the manufacturers say we can.  Further, it's got to be an issue for the banks, brokerage firms, credit agencies. If you are a newspaper and you employ reporters and they use a computer, how exactly are you guarding the confidentiality of your sources? If you're a confidential source, don't you have an interest when the reporter gives their computer manufacturer all their data to do with as they please? Imagine what you would do if it turned out there was a bug in a Netgear or Linksys router that allowed, under special circumstances, a mailicous person to gain access to the full content of your hard disk at any time. Would you have a problem with that? This is worse than Microsoft's neglect of malware that got me to stop using their computers. In that case it was Microsoft being neglegent. This time Apple itself is the cause of the problem. It's as if they planted a virus in their operating system that entitled them, under special circumstances, completely out of the user's control, to gain access to everything on your disk, with as much time as they want, with no way for you to prevent or even detect the intrusion.
