CVSS: 7.4EPSS: 3%CPEs: 2EXPL: 0CVE-2019-1543 – ChaCha20-Poly1305 with long nonces
https://notcve.org/view.php?id=CVE-2019-1543
06 Mar 2019 — ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input for every encryption operation. RFC 7539 specifies that the nonce value (IV) should be 96 bits (12 bytes). OpenSSL allows a variable nonce length and front pads the nonce with 0 bytes if it is less than 12 bytes. However it also incorrectly allows a nonce to be set of up to 16 bytes. In this case only the last 12 bytes are significant and any additional leading bytes are ignored. • http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00056.html • CWE-323: Reusing a Nonce, Key Pair in Encryption CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-330: Use of Insufficiently Random Values •
CVSS: 9.8EPSS: 8%CPEs: 13EXPL: 0CVE-2018-16395 – ruby: OpenSSL::X509:: Name equality check does not work correctly
https://notcve.org/view.php?id=CVE-2018-16395
03 Nov 2018 — An issue was discovered in the OpenSSL library in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. When two OpenSSL::X509::Name objects are compared using ==, depending on the ordering, non-equal objects may return true. When the first argument is one character longer than the second, or the second argument contains a character that is one less than a character in the same position of the first argument, the result of == will be true. This could be leveraged to cre... • http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00036.html • CWE-295: Improper Certificate Validation •

30 Oct 2018 — The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a (Affected 1.1.1). Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed in OpenSSL 1.0.2q (Affected 1.0.2-1.0.2p). • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00030.html • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-385: Covert Timing Channel •

30 Jan 2017 — The openssl gem for Ruby uses the same initialization vector (IV) in GCM Mode (aes-*-gcm) when the IV is set before the key, which makes it easier for context-dependent attackers to bypass the encryption protection mechanism. La openssl gem para Ruby utiliza el mismo vector de inicialización (IV) en el modo GCM (aes - * - gcm) cuando el IV se establece en versiones anteriores a la clave, lo que facilita que los atacantes dependiendo del contexto eludan el mecanismo de protección del cifrado.
