GnuTLS Security Vulnerabilities

GnuTLS is a free secure communications library for implementing the SSL, TLS and DTLS protocols. A security vulnerability exists in GnuTLS, which stems from a difference in response time for ciphertexts that are formatted incorrectly versus ciphertexts that are correctly padded, which could allow...

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...
