Description SMASH SMASH 2024-01-26 09:58:11 UTC

Description:
A timing side-channel in handling of RSA PKCS#1 v1.5 padded ciphertexts was discovered in the opencryptoki package. This side-channel can be used to perform RSA ciphertext decryption or signing without access to the private key. To achieve a successful decryption the attack would 
need to send a large amount of specifically crafted messages to a service that uses the vulnerable API.

Fixed in:
No fixed-in version yet, but a new release is expected in the next 3 weeks or so. Patches are already merged though.
