Description
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.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
