User EXEC privilege 1 — This is the default privilege when first connecting to the Cisco router and it provide only few commands to execute no authentication inside is required. List of commands are: connect: Opens a terminal session to another switch or router.

The information that can be viewed at this level is very limited. The heap is represented in memory as a double linked list of the specified format: The RED ZONE element inside the memory block is a static fixed value that whenever this value is changed in cause of any reason from a security research point of view, a buffer overflow occurred ; a message is popped out to the user says that a buffer overflow is detected and a restart is done.

The size element has the MSB most signficant bit set to 1 and its size is a word 2 bytes. The refcount element is used to track the usage of all processes that interacts with this memory block, this element has not seemed to be used and it's either 1 or 0. If the prev pointer is not null Check if the next pointer is point right after the end of this block and not point to some invalid memory or another block which is in the middle of the linked list and Check if the prev pointer in the block has a next pointer which is point to the this block.

Does the size make sense If one of those checks are not valid, the IOS will make the all system crash. If there are any exceptions, the ALL system is restarted. If there is a process hog and the process execution time is blocking, the scheduler there is timers for each process will shut down the all router. About No description or website provided.
