On Feb 7, 2008, an updated version of QuickTime was released (7.4.1). This update fixed an issue where visiting a malicious website could lead to an unexpected application termination or arbitrary code execution. See more details here.
QuickTime is installed on all Enterprise computers. Apple's QuickTime software allows your Enterprise computer to view graphics, videos, on-line video streams (ex: Candidate Interviews in the College), and more.
