New security vulnerability threatens Tiger

updated 03:20 pm EDT, Thu May 12, 2005

Tiger/QT exploit

A security vulnerability in Mac OS X 10.4 Tiger allows a malicious .mov file to . The exploit, which was discovered by David Remahl in Sweden, takes advantage "compositions," which have access to powerful tools known as "patches." Combining patches that provide advanced system information with patches that load information from the Internet allows an embedded .mov file to leak system details. A temporary workaround includes disabling the QuickTime plug-in and treating Quartz Composer files with suspicion. An alternative workaround involves disabling QTZ support in QuickTime by removing QuartzComposer.rcomponent in the QuickTime section of the system Library.

Leaked information:

  • Local user name (long and short)
  • Computer name
  • Local IP
  • OS / kernel version
  • CPU / RAM / GPU configuration
  • Names (human-readable) of Bonjour services on the local network
  • Local or system time
  • Volume of audio input
  • Lists of images (including pdfs) matching arbitrary spotlight queries
  • Lists of images (including pdfs) in specific directories (relative to / or ~)
  • The existence of image and movie files can indicate the existance of certain software packages

    Another exploit please!

    Unlike the Dashboard vulnerability, this ones seems a bit more concerning. However, I am once again confident Apple will patch this very fast. They have always been quick to respond, and I doubt this will be any different.

    Everytime I see one of these exploits, I think of hearing on the news about a critical Windows XP update that Microsoft released for an exploit that was found six months prior to the fix.

    No OS is going to be perfect but at least Apple seems to always be on their toes with Security patches and updates.

    Another security alert that needn't have been announced in such a way that it pretty much tells unscrupulous people who were not previously aware of it, exactly how to do it!

    They could have been a little less clear on the details, all right.

    But is it fatal

    05/12, 04:37pm reply

    The info is leaked, yes. That isn't good.

    But, it is fairly innocuous info… it isn't like an apple script co-opting Mail and spamming the 'verse.

    Here is hoping it is still addressed in short order.

    show and tell

    05/12, 04:38pm reply

    What's with show and tell. If I find a security issue I call apple and tell them. I also log it with apple's bug reporting. That's at the very least. I don't post anything about it in public for a good 2 weeks. Making a website to demo something, like the widget one, or this kind of report is negligent. If you tell people how to circumvent the security of a system and they do it you are responsible for it, regardless of how we define 'responsible'. In short, this kind of stuff (that almost seems orchestrated) will make the people doing wish that I had never been born if they come face to face with me.

    05/12, 04:39pm reply

    Leaked username and password might be considered fatal to some.

    No mention of leaked password at all. It provides basic information about the computer and various user accounts to someone who may be interested in breaking into it. That information would make it easier (than blindly guessing) to target the machine for a break-in but it would still require more effort.
