| CVE-2023-5981 | MÉDIO5.9 | A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. | 28/11/2023 |
| CVE-2023-0361 | ALTO7.4 | 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 | 15/02/2023 |
| CVE-2021-4209 | MÉDIO6.5 | 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. | 24/08/2022 |
| CVE-2022-2509 | ALTO7.5 | 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. | 01/08/2022 |
| CVE-2021-20232 | CRÍTICO9.8 | 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. | 12/03/2021 |
| CVE-2021-20231 | CRÍTICO9.8 | 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. | 12/03/2021 |
| CVE-2020-24659 | ALTO7.5 | 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 ca | 04/09/2020 |
| CVE-2020-13777 | ALTO7.4 | 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 | 04/06/2020 |
| CVE-2020-11501 | ALTO7.4 | 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 guarant | 03/04/2020 |
| CVE-2015-0294 | ALTO7.5 | GnuTLS before 3.3.13 does not validate that the signature algorithms match when importing a certificate. | 27/01/2020 |
| CVE-2015-8313 | MÉDIO5.9 | GnuTLS incorrectly validates the first byte of padding in CBC modes | 20/12/2019 |
| CVE-2019-3836 | ALTO7.5 | 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. | 01/04/2019 |
| CVE-2019-3829 | ALTO7.5 | 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. | 27/03/2019 |
| CVE-2018-16868 | MÉDIO5.6 | 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 | 03/12/2018 |
| CVE-2018-10846 | MÉDIO5.6 | 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. | 22/08/2018 |
| CVE-2018-10845 | MÉDIO5.9 | 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. | 22/08/2018 |
| CVE-2018-10844 | MÉDIO5.9 | 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. | 22/08/2018 |
