Apple QuickTime Java extensions (QTJava.dll), as used in Safari and other browsers, and when Java is enabled, allows remote attackers to execute arbitrary code via parameters to the toQTPointer method in quicktime.util.QTHandleRef, which can be used to modify arbitrary memory when creating QTPointerRef objects, as demonstrated during the "PWN 2 0WN" contest at CanSecWest 2007.
Las extensiones de Apple QuickTime Java (en la biblioteca QTJava .dll), como es usado en Safari y otros navegadores, y cuando Java está habilitado, permiten que los atacantes remotos ejecuten código arbitrario por medio de parámetros hacia el método toQTPointer en quicktime.util.QTHandleRef, que puede ser usado para modificar memoria arbitraria al crear objetos QTPointerRef, como se demostró durante el concurso "PWN 2 0WN" en CanSecWest 2007
This vulnerability allows attackers to execute arbitrary code on systems with vulnerable installations of Apple's QuickTime. User interaction is required to exploit this vulnerability in that the target must visit a malicious page.
The flaw exists within the QuickTime Java extensions (QTJava.dll), specifically the routine toQTPointer() exposed through quicktime.util.QTHandleRef. A lack of sanity checking on the parameters passed to this routine, through the Java Virtual Machine (JVM), allows an attacker to write arbitrary values to memory. This can be leveraged to execute arbitrary code under the context of the current user. Example code execution vectors include Microsoft Internet Explorer, Mozilla Firefox and Apple Safari. This vulnerability affects the latest versions of both the MacOS and Windows operating systems, including MacOS 10.4.9 and Windows Vista.
