There is no fixed version for Debian:unstable rust-rsa.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rust-rsa package and not the rust-rsa package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

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.
