DescriptionThis test case implements an unchecked write into a stack allocated buffer. The buffer is declared as a fixed size local variable within a function. Untrusted input is not properly sanitized or restricted before being copied into the target buffer, resulting in a buffer overflow. The overflow potentially modifies other local variables, depending on the layout of the stack. If the stack grows downward, the overflow will eventually overwrite %eip, smashing the stack or setting it to a valid instruction.
