OpenSSL is vulnerable to information disclosure. It is possible because a CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message that was encrypted with the public RSA key can be recovered using a Bleichenbacher padding oracle attack after an attacker is notified with status of decryption attempt. The vulnerability only affect unless a certificate together with the private RSA key to the CMS_decrypt or PKCS7_decrypt functions to select the correct recipient info to decrypt are used.
