| CVE-2024-0553 | 0.00 | — | 0.02 | Jan 16, 2024 | A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the… | |||
| CVE-2023-0361 | 0.00 | — | 0.01 | Feb 15, 2023 | 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… | |||
| CVE-2021-4209 | 0.00 | — | 0.01 | Aug 24, 2022 | 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. | |||
| CVE-2022-2509 | 0.00 | — | 0.01 | Aug 1, 2022 | 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 | 0.00 | — | 0.03 | Mar 12, 2021 | 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 | 0.00 | — | 0.04 | Mar 12, 2021 | 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 | 0.00 | — | 0.04 | Sep 4, 2020 | 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… | |||
| CVE-2020-13777 | 0.00 | — | 0.18 | Jun 4, 2020 | 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… | |||
| CVE-2020-11501 | 0.00 | — | 0.03 | Apr 3, 2020 | 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… | |||
| CVE-2015-0294 | 0.00 | — | 0.02 | Jan 27, 2020 | GnuTLS before 3.3.13 does not validate that the signature algorithms match when importing a certificate. | |||
| CVE-2015-8313 | 0.00 | — | 0.02 | Dec 20, 2019 | GnuTLS incorrectly validates the first byte of padding in CBC modes | |||
| CVE-2019-3836 | 0.00 | — | 0.03 | Apr 1, 2019 | 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 | 0.00 | — | 0.59 | Mar 27, 2019 | 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-2018-16868 | 0.00 | — | 0.01 | Dec 3, 2018 | 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… | |||

| CVE-2014-8155 | 0.00 | — | 0.01 | Aug 14, 2015 | 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. | |||
| CVE-2015-0282 | 0.00 | — | 0.01 | Mar 24, 2015 | GnuTLS before 3.1.0 does not verify that the RSA PKCS #1 signature algorithm matches the signature algorithm in the certificate, which allows remote attackers to conduct downgrade attacks via unspecified vectors. | |||
| CVE-2014-8564 | 0.00 | — | 0.03 | Nov 13, 2014 | The _gnutls_ecc_ansi_x963_export function in gnutls_ecc.c in GnuTLS 3.x before 3.1.28, 3.2.x before 3.2.20, and 3.3.x before 3.3.10 allows remote attackers to cause a denial of service (out-of-bounds write) via a crafted (1) Elliptic Curve Cryptography (ECC) certificate or (2)… | |||
| CVE-2014-1959 | 0.00 | — | 0.03 | Mar 7, 2014 | lib/x509/verify.c in GnuTLS before 3.1.21 and 3.2.x before 3.2.11 treats version 1 X.509 certificates as intermediate CAs, which allows remote attackers to bypass intended restrictions by leveraging a X.509 V1 certificate from a trusted CA to issue new certificates. | |||
| CVE-2009-5138 | 0.00 | — | 0.02 | Mar 7, 2014 | GnuTLS before 2.7.6, when the GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT flag is not enabled, treats version 1 X.509 certificates as intermediate CAs, which allows remote attackers to bypass intended restrictions by leveraging a X.509 V1 certificate from a trusted CA to issue new… |
