CIRCL's Kyber: timing side-channel (kyberslash2)

Impact On some platforms, when an attacker can time decapsulation of Kyber on forged cipher texts, they could possibly learn parts of the secret key. Does not apply to ephemeral usage, such as when used in the regular way in TLS. Patches Patched in 1.3.7. References - kyberslash.cr.yp.to...

Siemens SIMATIC and SCALANCE Products Encryption Strength (CVE-2022-4304)

A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages fo...
