The vulnerability is specific to static RSA cipher suites, and expected to be padding-independent.  The vulnerability allows an attacker to decrypt ciphertexts and forge signatures after probing with a large number of test observations. However the server\u2019s private key is not exposed.\n\nFIRST-EPSS: 0.000430000", "creation_timestamp": "2024-02-11T13:46:44.000000Z"}
