2019-03-27 CVE-2019-3829 A vulnerability was found in gnutls versions from 3.5.8 before 3.6.7. A memory corruption (double free) vulnerability in the certificate verification API. Any client or server application that verifies X.509 certificates with GnuTLS 3.5.8 or later is affected. Fedora, Gnutls 7.5
2019-04-01 CVE-2019-3836 It was discovered in gnutls before version 3.6.7 upstream that there is an uninitialized pointer access in gnutls versions 3.6.3 or later which can be triggered by certain post-handshake messages. Fedora, Gnutls, Leap 7.5
2020-04-03 CVE-2020-11501 GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 (2018-07-16) because of an error in a 2017-10-06 commit. The DTLS client always uses 32 '\0' bytes instead of a random value, and thus contributes no randomness to a DTLS negotiation. This breaks the security guarantees of the DTLS protocol. Ubuntu_linux, Debian_linux, Fedora, Gnutls, Leap 7.4
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
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
2009-11-09 CVE-2009-3555 The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions,...
