Apple on Wednesday released QuickTime 7.4.1, a recommended security update for all users of QuickTime 7.0 running Mac OS X 10.5 Leopard, Mac OS X 10.4.9 Tiger, Mac OS X 10.3.9 Panther, Windows XP SP2, and Windows Vista. The software update patches a vulnerability where visiting a malicious website could lead to an unexpected application termination or arbitrary code execution. 'A heap buffer overflow exists in QuickTime's handling of HTTP responses when RTSP tunneling is enabled,' Apple said.

'By enticing a user to visit a maliciously crafted webpage, an attacker may cause an unexpected application termination or arbitrary code execution.' QuickTime 7.4.1 addresses the issue through improved bounds checking.

The update is available as 55.5MB download for Leopard, a 51.7MB download for Tiger, a 50.4MB download for Panther, and a 22.3MB download for Windows Vista or XP SP2. I just (1.5 hours ago) installed this update on my PB G4 12 and Intel Mini, both on Leopard. No probs with the PB but the Mini just hung after I clicked restart. For over an hour I just had my desktop, no menu bar or icons, and an arrow mouse cursor. I finally figured I'd restart as something was amiss (the PB G4 took.

I did not want to reinstall so I restarted with the 10.5.1 HD selected as startup.

This time it did boot to the log in screen. I enter my password and get the setup utility (that thing that runs the first time you boot after install the first time), really odd! I quit the setup and it kicks me back to the login.

So I enter all the stuff in set up thinking if I jump through its hoops I'll be OK. After I go through all the setup assistant BS I get kicked back to the login screen again.

Any thoughts? Originally Posted by dopplerd I did finally get to boot to cd holding down 'c' on startup. I did not want to reinstall so I restarted with the 10.5.1 HD selected as startup.

After I go through all the setup assistant BS I get kicked back to the login screen again. Any thoughts? First, try this: The Setup Assistance is just a simple yes/no?or thereabouts?toggle in a text file.

If the hint above doesn't work put in you System Disk, hold down the 'C'. When it asks you to choose a langauge choose the appropriate one. This will not erase or install anything at this point.

You will now have a Menu Bar. Choose Disk Utility from Tools and Verify the Disk.

If the Verification fails then Reair. Also repair the Permissions while you are there (that isn't your problem, but they might be wonky).

After going through the endless loop of quitting the setup assistant a few times. I went back to the login screen and clicked shut down to deal with the broken computer tomorrow. As soon as I clicked shut down the 'Installing Software' window pops up and the QT update runs through and the computer shuts down. Upon restart everything is OK. While all my stuff is backed up it is a huge relief to not have to go through the install process.

Thanks for the suggestions. Originally Posted by dopplerd Weirdest thing happened. After going through the endless loop of quitting the setup assistant a few times. I went back to the login screen and clicked shut down to deal with the broken computer tomorrow.

Thanks for the suggestions.Jon That sounds like step two of the hint I posted from Apple. So far, I'm liking this new installation process with Leopard. DON'T INSTALL THIS! If, like me, you're on a PPC G5 iMac, 10.4.11. Lost audio on numerous audio-inclusive programs, including, and on SoundSlide site pages, as on my own page.
