Details

USN-6663-1 provided a security update for OpenSSL. This update provides the corresponding update for Ubuntu 24.04 LTS.

As a security improvement, OpenSSL will now return deterministic random bytes instead of an error when detecting wrong padding in PKCS#1 v1.5 RSA to prevent its use in possible Bleichenbacher timing attacks.
