Unspecified vulnerability in Apple QuickTime before 7.6 allows remote attackers to cause a denial of service (application termination) and possibly execute arbitrary code via a crafted H.263 encoded movie file that triggers memory corruption.

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.

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.

Stack-based buffer overflow in Apple QuickTime before 7.3.1, as used in QuickTime Player on Windows XP and Safari on Mac OS X, allows remote Real Time Streaming Protocol (RTSP) servers to execute arbitrary code via an RTSP response with a long Content-Type header.

Heap-based buffer overflow in Apple QuickTime before 7.1.5 allows remote user-assisted attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted MIDI file.

Integer overflow in Apple QuickTime before 7.1.5 allows remote user-assisted attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted QuickTime movie with a User Data Atom (UDTA) with an Atom size field with a large value.

Integer overflow in Apple QuickTime before 7.1.5, when installed on Windows operating systems, allows remote user-assisted attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted 3GP video file.

Cross-zone scripting vulnerability in Apple Quicktime 3 to 7.1.3 allows remote user-assisted attackers to execute arbitrary code and list filesystem contents via a QuickTime movie (.MOV) with an HREF Track (HREFTrack) that contains an automatic action tag with a local URI, which is executed in a local zone during preview, as exploited by a MySpace worm.

Stack-based buffer overflow in Apple QuickTime before 7.1 allows remote attackers to execute arbitrary code via a crafted QuickDraw PICT image format file containing malformed font information.
