Apple today released security updates for the Windows version of Quicktime. The update is available from the Apple Downloads site.
The patch affects users of QuickTime 7.2 on Windows Vista, XP SP2, and addresses the vulnerability in CVE-2007-4673. Currently, viewing maliciously crafted Quicktime files may lead to arbitrary code execution. "A command injection issue exists in QuickTime's handling of URLs in the qtnext field in files with QTL content. By enticing a user to open a specially crafted file, an attacker may cause an application to be launched with controlled command line arguments, which may lead to arbitrary code execution," Apple describes.
