DescriptionThis test case implements an unchecked write into a buffer that is contained within stack-allocated struct. The struct contains a function pointer, a fixed-size buffer, and another function pointer. Untrusted input is not properly sanitized or restricted before being copied into the target buffer, resulting in a buffer overflow. The overflow will destroy one of the function pointers either side of the buffer. The weakness then accesses those pointers, resulting in a crash or execution of attacker-specified code.
