RustCrypto/RSA vulnerable to a Marvin Attack via key recovery through timing sidechannels
Summary
RustCrypto/RSA vulnerable to a Marvin Attack via key recovery through timing sidechannels
Original description
The description as published by the source.
RustCrypto/RSA is a portable RSA implementation in pure Rust. Due to a non-constant-time implementation, information about the private key is leaked through timing information which is observable over the network. An attacker may be able to use that information to recover the key. There is currently no fix available. As a workaround, avoid using the RSA crate in settings where attackers are able to observe timing information, e.g. local use on a non-compromised computer.
