Description

Mozilla Firefox contains a race condition error. The NPObjWrapper_NewResolve function (nsJSNPRuntime.cpp) in xul.dll may dereference already freed memory when navigating away from a web page while loading a Java applet. This may allow a context-dependent attacker to potentially execute arbitrary code on a user's system.
