The problem description give us asm2(0x9,0x1e) and the asm source code. Read through the code end up in a loop, once the loop breaks we got the return value, which is the flag.
<+20>: add DWORD PTR [ebp-0x4],0x1
<+24>: add DWORD PTR [ebp-0x8],0xa9
<+31>: cmp DWORD PTR [ebp-0x8],0x47a6
<+38>: jle 0x501 <asm2+20>
Rewrite the function in Python
def asm2(a, b):
while a <= 0x47a6:
b += 1
a += 0xa9
return b
Invoke asm2 with given parameters to get the result.
print(asm2(0x9,0x1e))
