Get a look at Apple’s full descriptions of issues and fixes at their site: Security Update 2007-009
The QuickTime vulnerability originally reported on November 15 seems to have been spotted in the wild. This is not good news.
Apple made a decision to change the firewall settings in Leopard, provoking some serious questions about the security of this new OS. This latest security issue puts a spotlight on what may become a real thorn in Apple’s side.
This from Symantec:
Originally, the flaw was disclosed on November 23, 2007 by Polish security researcher Krystian Kloskowski and since then we have seen number of exploits targeting the vulnerability being released to the public. But now the exploit is active and in the wild, meaning web surfers are in danger of being attacked. Our current analysis is also leading us to believe that there may be multiple attacks in existence. Further investigation is currently under way to confirm this.
Let me briefly explain what we have seen. The attack we have confirmed today begins with the popular IFRAME. An IFRAME code that causes the browser to make an additional request to another URL, is embedded in a porn site. Without knowledge, users visiting this site are redirected to the malicious site serving the exploit. Currently, the malware that is downloaded by the exploit is detected by Symantec as Downloader. We are still studying the attack in depth, so look out for more information at a later time.
Since a patch to correct the issue has yet to be released, we advise users to be cautious when browsing the web. For those of you seeking extra protection, we also recommend the following options:
- Run web browsers at the highest security settings possible
- Disable Apple QuickTime as a registered RTSP protocol handler.
- Filter outgoing activity over common RTSP ports, including TCP port 554 and UDP ports 6970-6999.
The casual user of Apple’s new operating system, Leopard, may not be aware that unlike in Tiger, the firewall is off by default. To turn it on, you’ll need to go to System Preferences/Security/Firewall tab.

This is a new interface which lets you specify firewall blocking by application rather than ports or services (unlike Tiger). There have been several reports that Leopard’s firewall does not behave like Tiger’s. In some cases, it appears that it is not blocking certain services indicated by the settings.
Stay tuned for ongoing information regarding Leopard’s firewall issues, including some other security issues arising from Leopard’s Screen Sharing capabilities.
As the debut of Apple’s latest operating system nears, the rumblings about incompatibilities and problems increases. Although the new features are impressive, the problems and barriers to easy upgrade for exiting Tiger users is making quick adoption more difficult.
It’s not clear to me that this new OS will make my life easier/better in the educational environment I manage. For the first time, I will be testing this OS on a non-essential machine, and watching carefully the feedback from folks on several online forums. My move to Leopard will be slow and careful, despite my enthusiasm for new technology.
