It's not a complete answer because an adversary needs control on the random choice of a signing algorithm. First let me define ElGamal signature to not get lost in notation. $x \in N$ is the secret key. $p$ is a prime, it defines $Z_p^*$. $g$ is a generator of $Z_p^*$. $y=g^x$ and the public key is $(p, g, g^x)$. Then $k$ is picked at random from ...
