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
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
2018-08-22 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-2018-10844 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
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 N/A
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 N/A
