CVE-2022-4304 – Timing Oracle in RSA Decryption

https://notcve.org/view.php?id=CVE-2022-4304

07 Feb 2023 — 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 for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE. For example, in a TLS connection, RSA is commonly used by a client to send an encrypted pre-master secret to the serve... • https://github.com/Trinadh465/Openssl-1.1.1g_CVE-2022-4304 • CWE-203: Observable Discrepancy •
