2020-06-04 CVE-2020-13777 GnuTLS 3.6.x before 3.6.14 uses incorrect cryptography for encrypting a session ticket (a loss of confidentiality in TLS 1.2, and an authentication bypass in TLS 1.3). The earliest affected version is 3.6.4 (2018-09-24) because of an error in a 2018-09-18 commit. Until the first key rotation, the TLS server always uses wrong data in place of an encryption key derived from an application. Ubuntu_linux, Debian_linux, Fedora, Gnutls 7.4
2020-09-04 CVE-2020-24659 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. Ubuntu_linux, Fedora, Gnutls, Leap 7.5
2021-03-12 CVE-2021-20231 A flaw was found in gnutls. A use after free issue in client sending key_share extension may lead to memory corruption and other consequences. Fedora, Gnutls, Active_iq_unified_manager, E\-Series_performance_analyzer, Enterprise_linux 9.8
2021-03-12 CVE-2021-20232 A flaw was found in gnutls. A use after free issue in client_send_params in lib/ext/pre_shared_key.c may lead to memory corruption and other potential consequences. Fedora, Gnutls, Enterprise_linux 9.8
2022-08-01 CVE-2022-2509 A vulnerability found in gnutls. This security flaw happens because of a double free error occurs during verification of pkcs7 signatures in gnutls_pkcs7_verify function. Debian_linux, Fedora, Gnutls, Enterprise_linux 7.5
2022-08-24 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. Gnutls, Active_iq_unified_manager, Hci_bootstrap_os, Solidfire_\&_hci_management_node, Enterprise_linux 6.5
2023-02-15 CVE-2023-0361 A timing side-channel in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption the attacker would need to send a large amount of specially crafted messages to the vulnerable server. By recovering the secret from the ClientKeyExchange message, the attacker would be able to decrypt the application data... Debian_linux, Fedora, Gnutls, Active_iq_unified_manager, Converged_systems_advisor_agent, Ontap_select_deploy_administration_utility, Enterprise_linux 7.4
2023-11-28 CVE-2023-5981 A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. Fedora, Gnutls, Linux 5.9
2024-01-16 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. Fedora, Gnutls, Enterprise_linux 7.5
2024-01-16 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. Debian_linux, Fedora, Gnutls, Active_iq_unified_manager 7.5
