CVE-2009-1390 3 Gnu, Mutt, Openssl 3 Gnutls, Mutt, Openssl 2026-04-23 N/A
Mutt 1.5.19, when linked against (1) OpenSSL (mutt_ssl.c) or (2) GnuTLS (mutt_ssl_gnutls.c), allows connections when only one TLS certificate in the chain is accepted instead of verifying the entire chain, which allows remote attackers to spoof trusted servers via a man-in-the-middle attack.
CVE-2009-2409 4 Gnu, Mozilla, Openssl and 1 more 7 Gnutls, Network Security Services, Openssl and 4 more 2026-04-23 N/A
The Network Security Services (NSS) library before 3.12.3, as used in Firefox; GnuTLS before 2.6.4 and 2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products support MD2 with X.509 certificates, which might allow remote attackers to spoof certificates by using MD2 design flaws to generate a hash collision in less than brute-force time. NOTE: the scope of this issue is currently limited because the amount of computation required is still large.
CVE-2008-1950 2 Gnu, Redhat 2 Gnutls, Enterprise Linux 2026-04-23 N/A
Integer signedness error in the _gnutls_ciphertext2compressed function in lib/gnutls_cipher.c in libgnutls in GnuTLS before 2.2.4 allows remote attackers to cause a denial of service (buffer over-read and crash) via a certain integer value in the Random field in an encrypted Client Hello message within a TLS record with an invalid Record Length, which leads to an invalid cipher padding length, aka GNUTLS-SA-2008-1-3.
CVE-2009-2730 2 Gnu, Redhat 2 Gnutls, Enterprise Linux 2026-04-23 N/A
libgnutls in GnuTLS before 2.8.2 does not properly handle a '\0' character in a domain name in the subject's (1) Common Name (CN) or (2) Subject Alternative Name (SAN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.
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-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-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-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-2017-7507 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-2017-5336 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-2017-5334 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-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-2016-7444 2 Gnu, Redhat 2 Gnutls, Enterprise Linux 2025-04-12 N/A
The gnutls_ocsp_resp_check_crt function in lib/x509/ocsp.c in GnuTLS before 3.4.15 and 3.5.x before 3.5.4 does not verify the serial length of an OCSP response, which might allow remote attackers to bypass an intended certificate validation mechanism via vectors involving trailing bytes left by gnutls_malloc.
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.

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-2015-0282 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-2014-3465 2 Gnu, Redhat 2 Gnutls, Enterprise Linux 2025-04-12 N/A
The gnutls_x509_dn_oid_name function in lib/x509/common.c in GnuTLS 3.0 before 3.1.20 and 3.2.x before 3.2.10 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted X.509 certificate, related to a missing LDAP description for an OID when printing the DN.
