Is this vulnerability remotely exploitable?

It can be, depending on deployment. If a remote attacker can feed crafted ciphertexts into a component that uses Jervis' RSA decryption and can observe distinct success/failure behaviors, then a Bleichenbacher-style attack may be mounted remotely.

What level of access does an attacker need to exploit this?

The attacker needs the ability to influence or supply ciphertexts that are decrypted by the vulnerable code and to observe how the system behaves in response (e.g., error messages, timing, or status codes). Direct access to the private key is not required.

What is the safest general fix pattern?

The safest pattern is to replace PKCS#1 v1.5 padding (PKCS1Encoding) with OAEP for all RSA encryption/decryption operations and ensure uniform, non-informative error handling for decryption failures. This reduces both algorithmic and implementation-level oracle risks.
