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-2017-7869 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-2017-5334 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-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-2017-5335 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-2017-7507 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-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-2014-8564 4 Canonical, Gnu, Opensuse and 1 more 8 Ubuntu Linux, Gnutls, Opensuse and 5 more 2025-04-12 N/A
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) certificate signing requests (CSR), related to generating key IDs.
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-2015-6251 2 Debian, Gnu 2 Debian Linux, Gnutls 2025-04-12 N/A
Double free vulnerability in GnuTLS before 3.3.17 and 3.4.x before 3.4.4 allows remote attackers to cause a denial of service via a long DistinguishedName (DN) entry in a 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-2014-3467 5 Debian, F5, Gnu and 2 more 17 Debian Linux, Arx, Arx Firmware and 14 more 2025-04-12 N/A
Multiple unspecified vulnerabilities in the DER decoder in GNU Libtasn1 before 3.6, as used in GnuTLS, allow remote attackers to cause a denial of service (out-of-bounds read) via crafted ASN.1 data.
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.
