Python-RSA before 4.1 ignores leading ‘\0’ bytes during decryption of
ciphertext. This could conceivably have a security-relevant impact, e.g.,
by helping an attacker to infer that an application uses Python-RSA, or if
the length of accepted ciphertext affects application behavior (such as by
causing excessive memory allocation).
