Apple QuickTime Prior To 7.7.1 Movie File Handling Remote Code Execution Vulnerability
Apple QuickTime is prone to a remote code-execution vulnerability due to a signedness issue.
The problem occurs when handling a specially crafted movie file. Successful exploits may allow attackers to execute arbitrary code in the context of the currently logged-in user; failed exploit attempts may cause denial-of-service conditions.
Versions prior to QuickTime 7.7.1 are vulnerable on Windows 7, Vista, and XP.
NOTE: This issue was previously discussed in BID 50388 (Apple QuickTime Prior To 7.7.1 Multiple Arbitrary Code Execution Vulnerabilities) but has been given its own record to better document it.
