Low (2.7) in rustcrypto rsa. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in rsa 0.9.10.
The `rsa` crate is an RSA implementation written in rust. Prior to version 0.9.10, when creating a RSA private key from its components, the construction panics instead of returning an error when one of the primes is `1`. Version 0.9.10 fixes the issue.
