No affected components available
The encryption and decryption process were vulnerable against the Bleichenbacher's attack, which is a padding oracle vulnerability disclosed in the 98'. The issue was about the wrong padding utilized, which allowed to retrieve the encrypted content. The OPENSSL_PKCS1_PADDING version, aka PKCS v1.5 was vulnerable (is the one set by default when using openssl_* methods), while the PKCS v2.0 isn't anymore (it's also called OAEP).
