Vulnerability Summary Fixed by
VCID-2312-ktjb-zbee
Aliases:
CVE-2024-12243
A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially crafted certificate, causing GnuTLS to become unresponsive or slow, resulting in a denial-of-service condition.
3.7.9-2+deb12u4
Affected by 0 other vulnerabilities.

Aliases:
CVE-2024-28835
GNUTLS-SA-2024-01-23
A flaw has been discovered in GnuTLS where an application crash can be induced when attempting to verify a specially crafted .pem bundle using the "certtool --verify-chain" command.
3.7.9-2+deb12u4
Affected by 0 other vulnerabilities.
VCID-71jj-shy8-rbee
Aliases:
CVE-2025-32988
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.
3.7.9-2+deb12u4
Affected by 0 other vulnerabilities.
VCID-7red-s61z-nfbp
Aliases:
CVE-2024-0567
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.
3.7.1-5+deb11u5
Affected by 7 other vulnerabilities.
VCID-96eb-39cr-8ye6
Aliases:
CVE-2024-28834
GNUTLS-SA-2023-12-04
A flaw was found in GnuTLS. The Minerva attack is a cryptographic vulnerability that exploits deterministic behavior in systems like GnuTLS, leading to side-channel leaks. In specific scenarios, such as when using the GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE flag, it can result in a noticeable step in nonce size from 513 to 512 bits, exposing a potential timing side-channel.

Affected by 0 other vulnerabilities.
VCID-ff27-ufpk-rkbe
Aliases:
CVE-2025-6395
A NULL pointer dereference flaw was found in the GnuTLS software in _gnutls_figure_common_ciphersuite().
3.7.9-2+deb12u4
Affected by 0 other vulnerabilities.
VCID-hxyg-8211-puc7
Aliases:
CVE-2025-32990
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.
3.7.9-2+deb12u4
Affected by 0 other vulnerabilities.
VCID-swus-ze2b-kugb
Aliases:
CVE-2024-0553
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.
3.7.1-5+deb11u5
Affected by 7 other vulnerabilities.

VCID-43bp-nbru-s3f6 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-2021-4209
VCID-b6ws-79hy-57dz 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-2021-20231
CVE-2021-20232
GNUTLS-SA-2021-03-10
VCID-fx82-w6d8-7fds 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 negotiation. This breaks the security guarantees of the DTLS protocol. CVE-2020-11501
GNUTLS-SA-2020-03-31
VCID-hehk-phng-n3bu 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 attacker would need to send a large amount of specially crafted messages to the vulnerable server. By recovering the secret from the ClientKeyExchange message, the attacker would be able to decrypt the application data exchanged over that connection. CVE-2023-0361
VCID-kkf9-tpvd-5bad 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 key rotation, the TLS server always uses wrong data in place of an encryption key derived from an application. CVE-2020-13777
GNUTLS-SA-2020-06-03
VCID-r2jk-zuzp-rfek 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-2022-2509
GNUTLS-SA-2022-07-07
VCID-xsf6-1qzj-t3gm 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 path, where the gnutls_deinit function is called after detecting a handshake failure. CVE-2020-24659
