Tie-In to Lab 2

• You will be given a vulnerable 64-bit binary containing a hidden win()-style function.
• Tasks:
• Identify the unbounded copy in the source / disassembly.
• Find the offset to the saved return address (cyclic pattern).
• Build padding + p64(win); add a ret gadget if movaps complains.
• Capture the flag, then write the fix: replace the unsafe call and re-test.
• Deliverable includes both the working exploit and the patched, non-vulnerable version.
