An attacker can decrypt ciphertexts by exploiting the Marvin security flaw. Exploiting this vulnerability requires the attacker to have access to a large number of ciphertexts encrypted with the same key.\r\r Workaround \r\rThe vulnerability can be mitigated by finding and replacing RSA and RSAOAEP decryption with another crypto library."
