CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 2CVE-2024-0567 – Gnutls: rejects certificate chain with distributed trust
https://notcve.org/view.php?id=CVE-2024-0567
A vulnerability was found in GnuTLS, where a cockpit (which uses gnuTLS) rejects a certificate chain with distributed trust. This issue occurs when validating a certificate chain with cockpit-certificate-ensure. This flaw allows an unauthenticated, remote client or attacker to initiate a denial of service attack. Se encontró una vulnerabilidad en GnuTLS, donde una cabina (que usa gnuTLS) rechaza una cadena de certificados con confianza distribuida. Este problema ocurre al validar una cadena de certificados con cockpit-certificate-ensure. • http://www.openwall.com/lists/oss-security/2024/01/19/3 https://access.redhat.com/errata/RHSA-2024:0533 https://access.redhat.com/errata/RHSA-2024:1082 https://access.redhat.com/errata/RHSA-2024:1383 https://access.redhat.com/errata/RHSA-2024:2094 https://access.redhat.com/security/cve/CVE-2024-0567 https://bugzilla.redhat.com/show_bug.cgi?id=2258544 https://gitlab.com/gnutls/gnutls/-/issues/1521 https://lists.fedoraproject.org/archives/list/package-announce@lists. • CWE-347: Improper Verification of Cryptographic Signature •
CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 1CVE-2024-0553 – Gnutls: incomplete fix for cve-2023-5981
https://notcve.org/view.php?id=CVE-2024-0553
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.

https://notcve.org/view.php?id=CVE-2021-4209
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 https://bugzilla.redhat.com/show_bug.cgi?id=2044156 https://gitlab.com/gnutls/gnutls/-/commit/3db352734472d851318944db13be73da61300568 https://gitlab.com/gnutls/gnutls/-/issues/1306 https://gitlab.com/gnutls/gnutls/-/merge_requests/1503 https://security.netapp.com/advisory/ntap-20220915-0005 • CWE-476: NULL Pointer Dereference •
