The CallComponentFunctionWithStorage function in Apple QuickTime before 7.5.5 does not properly handle a large entry in the sample_size_table in STSZ atoms, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted movie file.

Heap-based buffer overflow in Apple QuickTime before 7.5.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a QuickTime Virtual Reality (QTVR) movie file with crafted panorama atoms.

Stack-based buffer overflow in QuickTimeInternetExtras.qtx in an unspecified third-party Indeo v3.2 (aka IV32) codec for QuickTime, when used with Apple QuickTime before 7.5.5 on Windows, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted movie file.

Integer overflow in Apple QuickTime before 7.5.5 on Windows allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted PICT image, which triggers heap corruption.

Apple QuickTime before 7.4.5 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted ftyp atoms in a movie file, which triggers memory corruption.

Buffer overflow in Apple Quicktime Player 7.3.1.70 and other versions before 7.4.1, when RTSP tunneling is enabled, allows remote attackers to execute arbitrary code via a long Reason-Phrase response to an rtsp:// request, as demonstrated using a 404 error message.
