ENS DNSSEC Oracle Vulnerable to RSA Signature Forgery via Missing PKCS#1 v1.5 Padding Validation

Impact The RSASHA256Algorithm and RSASHA1Algorithm contracts fail to validate PKCS1 v1.5 padding structure when verifying RSA signatures. The contracts only check if the last 32 or 20 bytes of the decrypted signature match the expected hash. This enables Bleichenbacher's 2006 signature forgery...
