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. Gnutls, Enterprise_linux 7.5
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,... Http_server, Ubuntu_linux, Debian_linux, Nginx, Fedora, Gnutls, Nss, Openssl N/A
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
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
2018-12-03 CVE-2018-16868 A Bleichenbacher type side-channel based padding oracle attack was found in the way gnutls handles verification of RSA decrypted PKCS#1 v1.5 data. An attacker who is able to run process on the same physical core as the victim process, could use this to extract plaintext or in some cases downgrade any TLS connections to a vulnerable server. Gnutls 5.6
2014-06-05 CVE-2014-3469 The (1) asn1_read_value_type and (2) asn1_read_value functions in GNU Libtasn1 before 3.6 allows context-dependent attackers to cause a denial of service (NULL pointer dereference and crash) via a NULL value in an ivalue argument. Debian_linux, Gnutls, Libtasn1, Enterprise_linux_desktop, Enterprise_linux_eus, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_tus, Enterprise_linux_workstation, Virtualization, Linux_enterprise_desktop, Linux_enterprise_high_availability_extension, Linux_enterprise_server, Linux_enterprise_software_development_kit N/A
2014-06-05 CVE-2014-3467 Multiple unspecified vulnerabilities in the DER decoder in GNU Libtasn1 before 3.6, as used in GnuTLS, allow remote attackers to cause a denial of service (out-of-bounds read) via crafted ASN.1 data. Debian_linux, Arx_firmware, Gnutls, Libtasn1, Enterprise_linux_desktop, Enterprise_linux_eus, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_tus, Enterprise_linux_workstation, Virtualization, Linux_enterprise_desktop, Linux_enterprise_high_availability_extension, Linux_enterprise_server, Linux_enterprise_software_development_kit N/A
2014-06-05 CVE-2014-3468 The asn1_get_bit_der function in GNU Libtasn1 before 3.6 does not properly report an error when a negative bit length is identified, which allows context-dependent attackers to cause out-of-bounds access via crafted ASN.1 data. Debian_linux, Arx_firmware, Gnutls, Libtasn1, Enterprise_linux_desktop, Enterprise_linux_eus, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_tus, Enterprise_linux_workstation, Virtualization, Linux_enterprise_desktop, Linux_enterprise_high_availability_extension, Linux_enterprise_server, Linux_enterprise_software_development_kit N/A
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. Fedora, Gnutls 7.5
