| 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-2025-32990 | 2 Gnu, Redhat | 9 Gnutls, Ceph Storage, Discovery and 6 more | 2025-12-01 | 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-2025-32989 | 2 Gnu, Redhat | 9 Gnutls, Ceph Storage, Discovery and 6 more | 2025-12-01 | 5.3 Medium |
| A heap-buffer-overread vulnerability was found in GnuTLS in how it handles the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension during X.509 certificate parsing. This flaw allows a malicious user to create a certificate containing a malformed SCT extension (OID 1.3.6.1.4.1.11129.2.4.2) that contains sensitive data. This issue leads to the exposure of confidential information when GnuTLS verifies certificates from certain websites when the certificate (SCT) is not checked correctly. | ||||
| CVE-2025-32988 | 2 Gnu, Redhat | 9 Gnutls, Ceph Storage, Discovery and 6 more | 2025-12-01 | 6.5 Medium |
| A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS due to incorrect ownership handling in the export logic of Subject Alternative Name (SAN) entries containing an otherName. If the type-id OID is invalid or malformed, GnuTLS will call asn1_delete_structure() on an ASN.1 node it does not own, leading to a double-free condition when the parent function or caller later attempts to free the same structure. This vulnerability can be triggered using only public GnuTLS APIs and may result in denial of service or memory corruption, depending on allocator behavior. | ||||
| 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-2024-0553 | 3 Fedoraproject, Gnu, Redhat | 6 Fedora, Gnutls, Enterprise Linux and 3 more | 2025-11-20 | 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-2023-5981 | 3 Fedoraproject, Gnu, Redhat | 7 Fedora, Gnutls, Enterprise Linux and 4 more | 2025-11-06 | 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-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-2017-5334 | 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-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-2014-8155 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2025-04-12 | N/A |
| 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 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2025-04-12 | N/A |
| 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-2014-3468 | 5 Debian, F5, Gnu and 2 more | 17 Debian Linux, Arx, Arx Firmware and 14 more | 2025-04-12 | N/A |
| 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. | ||||
| CVE-2015-3308 | 2 Canonical, Gnu | 2 Ubuntu Linux, Gnutls | 2025-04-12 | N/A |
| Double free vulnerability in lib/x509/x509_ext.c in GnuTLS before 3.3.14 allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted CRL distribution point. | ||||
| 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. | ||||
