Question

What are heap overflows and why are they less common than stack overflows?

a.

Heap overflows occur when the programmer miscalculates the number of bytes needed to hold a particular user-supplied buffer in memory, and are less common because heap block sizes are dynamically calculated to fit incoming data

b.

Heap overflows occur when the size of a heap block is predefined, and are less common because programmers rarely hard-code the size of a heap block when they have variably sized incoming data

c.

Heap overflows occur when an outsider is allowed to provide a string that is copied into a fixed-sized internal buffer, and are less common because heap blocks typically have a dynamic size

d.

Heap overflows occur when the caller can supply a string that is too long for the target buffer, and are less common because heap blocks are almost always dynamically calculated to be large enough to fit incoming data
