|---|---|---|---|---|
| CVE-2025-32990 | 2 Gnu, Redhat | 10 Gnutls, Ceph Storage, Discovery and 7 more | 2026-04-20 | 6.5 Medium |
| A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic within the certtool utility. When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service (DoS) that could potentially crash the system. | ||||
| CVE-2006-4790 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2026-04-16 | N/A |
| verify.c in GnuTLS before 1.4.4, when using an RSA key with exponent 3, does not properly handle excess data in the digestAlgorithm.parameters field when generating a hash, which allows remote attackers to forge a PKCS #1 v1.5 signature that is signed by that RSA key and prevents GnuTLS from correctly verifying X.509 and other certificates that use PKCS, a variant of CVE-2006-4339. | ||||
| CVE-2005-1431 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2026-04-16 | N/A |
| The "record packet parsing" in GnuTLS 1.2 before 1.2.3 and 1.0 before 1.0.25 allows remote attackers to cause a denial of service, possibly related to padding bytes in gnutils_cipher.c. | ||||
| CVE-2004-2531 | 1 Gnu | 1 Gnutls | 2026-04-16 | N/A |
| X.509 Certificate Signature Verification in Gnu transport layer security library (GnuTLS) 1.0.16 allows remote attackers to cause a denial of service (CPU consumption) via certificates containing long chains and signed with large RSA keys. | ||||
| CVE-2023-5981 | 4 Debian, Fedoraproject, Gnu and 1 more | 8 Debian Linux, Fedora, Gnutls and 5 more | 2026-03-25 | 5.9 Medium |
| 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. | ||||
| CVE-2024-0553 | 3 Fedoraproject, Gnu, Redhat | 6 Fedora, Gnutls, Enterprise Linux and 3 more | 2026-03-24 | 7.5 High |
| 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 RSA-PSK key exchange, potentially leading to the leakage of sensitive data. CVE-2024-0553 is designated as an incomplete resolution for CVE-2023-5981. | ||||
| CVE-2021-20232 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Gnutls, Enterprise Linux | 2025-12-03 | 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-2022-2509 | 4 Debian, Fedoraproject, Gnu and 1 more | 4 Debian Linux, Fedora, Gnutls and 1 more | 2025-12-02 | 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-2024-0567 | 5 Debian, Fedoraproject, Gnu and 2 more | 9 Debian Linux, Fedora, Gnutls and 6 more | 2025-11-20 | 7.5 High |
| A vulnerability was found in GnuTLS, where a cockpit (which uses gnuTLS) rejects a certificate chain with distributed trust. This issue occurs when validating a certificate chain with cockpit-certificate-ensure. This flaw allows an unauthenticated, remote client or attacker to initiate a denial of service attack. | ||||
| CVE-2017-7507 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2025-04-20 | N/A |
| 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. | ||||
| CVE-2016-4456 | 1 Gnu | 1 Gnutls | 2025-04-20 | 7.5 High |
| The "GNUTLS_KEYLOGFILE" environment variable in gnutls 3.4.12 allows remote attackers to overwrite and corrupt arbitrary files in the filesystem. | ||||
| CVE-2017-5336 | 3 Gnu, Opensuse, Redhat | 3 Gnutls, Leap, Enterprise Linux | 2025-04-20 | N/A |
| Stack-based buffer overflow in the cdk_pk_get_keyid function in lib/opencdk/pubkey.c in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allows remote attackers to have unspecified impact via a crafted OpenPGP certificate. | ||||
| CVE-2017-7869 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2025-04-20 | N/A |
| GnuTLS before 2017-02-20 has an out-of-bounds write caused by an integer overflow and heap-based buffer overflow related to the cdk_pkt_read function in opencdk/read-packet.c. This issue (which is a subset of the vendor's GNUTLS-SA-2017-3 report) is fixed in 3.5.10. | ||||
| CVE-2017-5337 | 3 Gnu, Opensuse, Redhat | 3 Gnutls, Leap, Enterprise Linux | 2025-04-20 | N/A |
| Multiple heap-based buffer overflows in the read_attribute function in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allow remote attackers to have unspecified impact via a crafted OpenPGP certificate. | ||||
| CVE-2017-5335 | 3 Gnu, Opensuse, Redhat | 3 Gnutls, Leap, Enterprise Linux | 2025-04-20 | N/A |
| The stream reading functions in lib/opencdk/read-packet.c in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allow remote attackers to cause a denial of service (out-of-memory error and crash) via a crafted OpenPGP certificate. | ||||
| CVE-2017-5334 | 3 Gnu, Opensuse, Redhat | 3 Gnutls, Leap, Enterprise Linux | 2025-04-20 | N/A |
| Double free vulnerability in the gnutls_x509_ext_import_proxy function in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allows remote attackers to have unspecified impact via crafted policy language information in an X.509 certificate with a Proxy Certificate Information extension. | ||||
| CVE-2014-1959 | 1 Gnu | 1 Gnutls | 2025-04-12 | N/A |
| 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-2014-3469 | 4 Debian, Gnu, Redhat and 1 more | 15 Debian Linux, Gnutls, Libtasn1 and 12 more | 2025-04-12 | N/A |
| 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. | ||||
| CVE-2014-3466 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2025-04-12 | N/A |
| Buffer overflow in the read_server_hello function in lib/gnutls_handshake.c in GnuTLS before 3.1.25, 3.2.x before 3.2.15, and 3.3.x before 3.3.4 allows remote servers to cause a denial of service (memory corruption) or possibly execute arbitrary code via a long session id in a ServerHello message. | ||||
| CVE-2009-5138 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2025-04-12 | N/A |
| 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 certificates, a different vulnerability than CVE-2014-1959. | ||||
