CVSS: 7.8EPSS: 0%CPEs: 4EXPL: 1CVE-2024-0553 – Gnutls: incomplete fix for cve-2023-5981
https://notcve.org/view.php?id=CVE-2024-0553
16 Jan 2024 — A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange, potentially leading to the leakage of sensitive data. CVE-2024-0553 is designated as an incomplete resolution for CVE-2023-5981. Se encontró una vulnerabilidad en GnuTLS. • http://www.openwall.com/lists/oss-security/2024/01/19/3 • CWE-203: Observable Discrepancy •

https://notcve.org/view.php?id=CVE-2021-4209
05 Aug 2022 — A NULL pointer dereference flaw was found in GnuTLS. As Nettle's hash update functions internally call memcpy, providing zero-length input may cause undefined behavior. This flaw leads to a denial of service after authentication in rare circumstances. Se ha encontrado un fallo de desreferencia de puntero NULL en GnuTLS. Como las funciones de actualización de hash de Nettle llaman internamente a memcpy, proporcionar una entrada de longitud cero puede causar un comportamiento indefinido. • https://access.redhat.com/security/cve/CVE-2021-4209 • CWE-476: NULL Pointer Dereference •

CVSS: 7.5EPSS: 0%CPEs: 6EXPL: 1CVE-2020-24659 – gnutls: Heap buffer overflow in handshake with no_renegotiation alert sent
https://notcve.org/view.php?id=CVE-2020-24659
04 Sep 2020 — An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a no_renegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure.
