Check out C Subtleties! phr33dom (http://phr33dom.wordpress.com/2012/07/04/c-subtleties/) . I have discussed some arcane concepts of C that every _good_ programmer in C should know to avoid security bugs.

@fb1h2s: Thanks bro..
@[s] : I don't have dangling exploitation samples, i guess it will be dependent on a lot of parameters, one place where dangling pointer occurs often is in C++, when a member variable is dynamically allocated and then you are copying the object to another object of the same class. By default, c++ performs shallow copy,so there is a high probability that a dangling pointer issue might occur here. Remediation is to implement your own copy constructor and also the override the '=' operator when you have a class member variable whose memory is dynamically allocated.

@H@CK3R_ADI : Thanks , try solving the 2 sample programs I have given in my blog.
