Apple today released QuickTime 7.6.7 for Windows, bringing a fix for a single security issue that could be exploited by a maliciously crafted movie file.
A stack buffer overflow exists in QuickTime's error logging. Viewing a maliciously crafted movie file may lead to an unexpected application termination or arbitrary code execution. This issue is addressed by disabling debug logging. This issue does not affect Mac OS X systems.
The update weighs in at 32.28 MB and requires Windows 7, Vista, or XP (SP2 or later).
