Description:
A vulnerability was reported in Mozilla Firefox. A remote user can cause arbitrary code to be executed on the target user's system.
A remote user can create specially crafted HTML that, when loaded by the target user, will navigate away from a web page while a Java applet is loading to cause the applet to be deleted and then later called, potentially writing freed memory and executing arbitrary code on the target system. The code will run with the privileges of the target user.
The vulnerability resides in NPObjWrapper_NewResolve and occurs when accessing the properties of an NPObject.
Firefox 2.x is not affected.
