Apple QuickTime Player is reported prone to remote denial of service attack (exploitable via remotely originated content). A missing movie attribute is interpreted as an extension, but the absence of the extension is not flagged as an error, resulting in a de-reference of a NULL pointer. This will cause a denial of service against any application loading remotely-originated content. Software affected: QuickTime package 7.0.1 for Mac OS X 10.3, QuickTime package 7.0.1 for Mac OS X 10.4, QuickTime package 6.5.2 for Mac OS X 10.3, QuickTime package 6.5.2 for Mac OS X 10.2, QuickTime package 7x for Windows.
