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,... Http_server, Ubuntu_linux, Debian_linux, Nginx, Fedora, Gnutls, Nss, Openssl N/A
2010-05-24 CVE-2006-7239 The _gnutls_x509_oid2mac_algorithm function in lib/gnutls_algorithms.c in GnuTLS before 1.4.2 allows remote attackers to cause a denial of service (crash) via a crafted X.509 certificate that uses a hash algorithm that is not supported by GnuTLS, which triggers a NULL pointer dereference. Gnutls N/A
2015-08-14 CVE-2014-8155 GnuTLS before 2.9.10 does not verify the activation and expiration dates of CA certificates, which allows man-in-the-middle attackers to spoof servers via a certificate issued by a CA certificate that is (1) not yet valid or (2) no longer valid. Gnutls N/A
2018-08-22 CVE-2018-10844 It was found that the GnuTLS implementation of HMAC-SHA-256 was vulnerable to a Lucky thirteen style attack. Remote attackers could use this flaw to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data using crafted packets. Ubuntu_linux, Debian_linux, Fedora, Gnutls, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_workstation 5.9
2018-08-22 CVE-2018-10845 It was found that the GnuTLS implementation of HMAC-SHA-384 was vulnerable to a Lucky thirteen style attack. Remote attackers could use this flaw to conduct distinguishing attacks and plain text recovery attacks via statistical analysis of timing data using crafted packets. Ubuntu_linux, Debian_linux, Fedora, Gnutls, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_workstation 5.9
2018-08-22 CVE-2018-10846 A cache-based side channel in GnuTLS implementation that leads to plain text recovery in cross-VM attack setting was found. An attacker could use a combination of "Just in Time" Prime+probe attack in combination with Lucky-13 attack to recover plain text using crafted packets. Ubuntu_linux, Debian_linux, Fedora, Gnutls, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_workstation 5.6
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
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
