Apple has released QuickTime 7.6.7 for Windows to address a vulnerability. This vulnerability is due to a stack buffer overflow that exists in QuickTime error logging. By convincing a user to open a specially crafted movie file, a remote attacker may be able to execute arbitrary code or cause a denial-of-service condition.
US-CERT encourages users and administrators to review Apple article HT4290 and update to QuickTime 7.6.7 to help mitigate the risks.
