Test case 1507

Description

Vulnerability to an exploit using the frontlink technique. Similar to unlink(), the frontlink() code segment can be exploited to write data supplied by the attacker to an address also supplied by the attacker. The attacker supplies the address of a memory chunk. The attacker arranges for the first four bytes of this memory chunk to contain executable code.
