Apple releases QuickTime 7.4.1 for Leopard, Tiger and Panther

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.
