.NET Forum / .NET Framework / CLR / November 2006Memory access of unmanaged DLL
Hi! I need to know, how much power an unmanaged DLL has about the "managed memory". Can I access memory of the managed code from a loaded unmanaged DLL? The point is: Does a intruder, who injected code into the unmanged DLL via e.g. a buffer overflow, have the possibility to read and modify data in the managed memory? Thank you!

But an information leak is a problem even if it isn't reliable. > Mattias
