Daniel Bleichenbacher discovered an attack on PKCS #1 v1.5 signatures.
Where an RSA key with exponent 3 is used it may be possible for an attacker
to forge a PKCS #1 v1.5 signature that would be incorrectly verified by
implementations that do not check for excess data in the RSA exponentiation
result of the signature. (CVE-2006-4339)
