Apple has patched a bunch of bugs in QuickTime, updating it to version 7.3 for Windows and Macs.  Most of the bugs can be considered critical, except that Apple does not rate the flaws. 

However, some of the bugs could be exploited for “arbitrary code execution”, as Apple calls it.  This simply means that an attacker could run his own program on your PC, or in other words hijack your computer and take control of it.

QuickTime has been repeatedly patched against Java flaws.  Rather than patch it yet again, Apple has restricted QuickTime for Java in most cases.  QuickTime will no longer be accessible to untrusted Java code.

To update QuickTime, launch it and click Help, Update Existing Software.

iTunes was also updated to version 7.5, fixing performance and stability bugs.  To update both iTunes and QuickTime at once, launch iTunes and click Help, Check for Updates.
