CVE-2023-4421

CVE-2023-4421 concerns the NSS library’s handling of PKCS#1 v1.5 padding, where timing side-channel leakage exposed information about padding validity and message length. This could enable Bleichenbacher-like attacks, allowing an attacker to decrypt previously intercepted PKCS#1 v1.5 ciphertext (...

CVE-2023-45287

A flaw was found in the Golang crypto/tls standard library. In previous versions, the package was vulnerable to a Timing Side Channel attack by observing the time it took for RSA-based TLS key exchanges, which was not constant. This flaw allows a malicious user to gather information from the...

AZL-79088 CVE-2023-45287 affecting package golang 1.25.7-1

Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant time. RSA blinding was applied to prevent timing attacks, but analysis shows this may not have been fully effective. In particular it appears as if the removal of PKCS1 padding may leak timing...
