| CVE-2022-2509 | 4 Debian, Fedoraproject, Gnu and 1 more | 4 Debian Linux, Fedora, Gnutls and 1 more | 2024-02-04 | N/A | 7.5 HIGH |
| 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. | |||||
| CVE-2021-20232 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Gnutls, Enterprise Linux | 2024-02-04 | 7.5 HIGH | 9.8 CRITICAL |
| 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. | |||||
| CVE-2021-20231 | 4 Fedoraproject, Gnu, Netapp and 1 more | 5 Fedora, Gnutls, Active Iq Unified Manager and 2 more | 2024-02-04 | 7.5 HIGH | 9.8 CRITICAL |
| 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. | |||||
| CVE-2020-24659 | 4 Canonical, Fedoraproject, Gnu and 1 more | 4 Ubuntu Linux, Fedora, Gnutls and 1 more | 2024-02-04 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2020-13777 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2024-02-04 | 5.8 MEDIUM | 7.4 HIGH |
| 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. | |||||
| CVE-2020-11501 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2024-02-04 | 5.8 MEDIUM | 7.4 HIGH |
| 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. | |||||
| CVE-2015-0294 | 3 Debian, Gnu, Redhat | 3 Debian Linux, Gnutls, Enterprise Linux | 2024-02-04 | 5.0 MEDIUM | 7.5 HIGH |

| CVE-2015-8313 | 2 Debian, Gnu | 2 Debian Linux, Gnutls | 2024-02-04 | 4.3 MEDIUM | 5.9 MEDIUM |
| GnuTLS incorrectly validates the first byte of padding in CBC modes | |||||
| CVE-2019-3836 | 3 Fedoraproject, Gnu, Opensuse | 3 Fedora, Gnutls, Leap | 2024-02-04 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2019-3829 | 2 Fedoraproject, Gnu | 2 Fedora, Gnutls | 2024-02-04 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2018-10845 | 5 Canonical, Debian, Fedoraproject and 2 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2024-02-04 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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. | |||||
| CVE-2018-16868 | 1 Gnu | 1 Gnutls | 2024-02-04 | 3.3 LOW | 5.6 MEDIUM |
| 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. | |||||
| CVE-2018-10844 | 5 Canonical, Debian, Fedoraproject and 2 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2024-02-04 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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. | |||||

| 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. | |||||
| CVE-2017-7507 | 1 Gnu | 1 Gnutls | 2024-02-04 | 5.0 MEDIUM | 7.5 HIGH |
| GnuTLS version 3.5.12 and earlier is vulnerable to a NULL pointer dereference while decoding a status response TLS extension with valid contents. This could lead to a crash of the GnuTLS server application. | |||||
