Marvin Attack: potential key recovery through timing sidechannels

Details
Package rsa
Version 0.8.2
URL https://github.com/RustCrypto/RSA/issues/19#issuecomment-1822995643
Date 2023-11-22

Impact

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.

Patches

No patch is yet available, however work is underway to migrate to a fully constant-time implementation.

Workarounds

The only currently available workaround is to avoid using the rsa crate in settings where attackers are able to observe timing information, e.g. local use on a non-compromised computer is fine.

References

This vulnerability was discovered as part of the "Marvin Attack", which revealed several implementations of RSA including OpenSSL had not properly mitigated timing sidechannel attacks.

See advisory page for additional details.
