| CVE-2026-42014 | Med | 6.6 | < 3.8.13-1.1 | 3.8.13-1.1 | Jun 16, 2026 | A flaw was found in GnuTLS. The `gnutls_pkcs11_token_set_pin` function, used for changing the Security Officer PIN, can lead to a use-after-free vulnerability. This occurs when an attacker attempts to change the PIN with a NULL old PIN for a token that lacks a protected authentic | |
| CVE-2026-5419 | Low | 3.7 | < 3.8.13-1.1 | 3.8.13-1.1 | Jun 1, 2026 | A flaw was found in gnutls. The PKCS#7 padding check, performed during decryption, was not constant-time. This timing side-channel could allow a remote attacker to potentially leak sensitive information about the padding bytes through observable timing differences. This vulnerabi | |
| CVE-2026-5260 | Hig | 8.2 | < 3.8.13-1.1 | 3.8.13-1.1 | May 26, 2026 | A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS#11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information | |
| CVE-2026-42015 | Med | 5.3 | < 3.8.13-1.1 | 3.8.13-1.1 | May 26, 2026 | A flaw was found in gnutls. An off-by-one error exists in the PKCS#12 bag element bounds check. This vulnerability allows an remote attacker to write past the internal array of a PKCS#12 bag when appending to a bag that already contains 32 elements. This memory corruption could l | |
| CVE-2026-42013 | Hig | 8.2 | < 3.8.13-1.1 | 3.8.13-1.1 | May 26, 2026 | A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name (SAN) could cause the validation process to incorrectly fall back to checking the Common Name (CN) field. This could allow a remote attacker to bypass proper certificate validation, po | |
| CVE-2026-42012 | Hig | 7.1 | < 3.8.13-1.1 | 3.8.13-1.1 | May 26, 2026 | A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted certificate that contains Uniform Resource Identifier (URI) or Service (SRV) Subject Alternative Names (SANs). This could cause the certificate validation process to i | |
| CVE-2026-42009 | Hig | 7.5 | < 3.8.13-1.1 | 3.8.13-1.1 | May 18, 2026 | A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security (DTLS) packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequen | |
| CVE-2026-42011 | Hig | 7.4 | < 3.8.13-1.1 | 3.8.13-1.1 | May 7, 2026 | A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities (CAs) only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during | |
| CVE-2026-42010 | Hig | 7.1 | < 3.8.13-1.1 | 3.8.13-1.1 | May 7, 2026 | A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authe | |
| CVE-2026-33846 | Hig | 7.5 | < 3.8.13-1.1 | 3.8.13-1.1 | May 4, 2026 | A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in merge_handshake_packet() where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the message_length | |
| CVE-2026-3833 | Med | 6.5 | < 3.8.13-1.1 | 3.8.13-1.1 | Apr 30, 2026 | A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can explo | |
| CVE-2026-3832 | Low | 3.7 | < 3.8.13-1.1 | 3.8.13-1.1 | Apr 30, 2026 | A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol (OCSP) response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP | |
| CVE-2026-33845 | Hig | 7.5 | < 3.8.13-1.1 | 3.8.13-1.1 | Apr 30, 2026 | A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of | |
| CVE-2026-1584 | Hig | 7.5 | < 3.8.12-1.1 | 3.8.12-1.1 | Apr 9, 2026 | A flaw was found in gnutls. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted ClientHello message with an invalid Pre-Shared Key (PSK) binder value during the TLS handshake. This can lead to a NULL pointer dereference, causing the se | |
| CVE-2025-14831 | Med | 5.3 | < 3.8.12-1.1 | 3.8.12-1.1 | Feb 9, 2026 | A flaw was found in GnuTLS. This vulnerability allows a denial of service (DoS) by excessive CPU (Central Processing Unit) and memory consumption via specially crafted malicious certificates containing a large number of name constraints and subject alternative names (SANs). | |
| CVE-2025-9820 | Med | 4.0 | < 3.8.11-1.1 | 3.8.11-1.1 | Jan 26, 2026 | A flaw was found in the GnuTLS library, specifically in the gnutls_pkcs11_token_init() function that handles PKCS#11 token initialization. When a token label longer than expected is processed, the function writes past the end of a fixed-size stack buffer. This programming error c | |
| CVE-2025-6395 | Med | 6.5 | < 3.8.10-1.1 | 3.8.10-1.1 | Jul 10, 2025 | A NULL pointer dereference flaw was found in the GnuTLS software in _gnutls_figure_common_ciphersuite(). | |
| CVE-2025-32990 | Med | 6.5 | < 3.8.10-1.1 | 3.8.10-1.1 | Jul 10, 2025 | 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 | |
| CVE-2025-32989 | Med | 5.3 | < 3.8.10-1.1 | 3.8.10-1.1 | Jul 10, 2025 | 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 extensi | |
| CVE-2025-32988 | Med | 6.5 | < 3.8.10-1.1 | 3.8.10-1.1 | Jul 10, 2025 | 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() |
