Heap-based buffer overflow in Clip opcode parsing in Apple QuickTime before 7.4.5 on Windows allows remote attackers to execute arbitrary code via a crafted PICT image file.
Multiple stack-based buffer overflows in an ActiveX control in QTPlugin.ocx for Apple QuickTime 7.4.1 and earlier allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via long arguments to the (1) SetBgColor, (2) SetHREF, (3) SetMovieName, (4) SetTarget, and (5) SetMatrix methods.
Unspecified vulnerability in Apple QuickTime before 7.4 allows remote attackers to cause a denial of service (application termination) and execute arbitrary code via a movie file with Image Descriptor (IDSC) atoms containing an invalid atom size, which triggers memory corruption.
