Off-by-one error in the dane_raw_tlsa in the DANE library (libdane) in GnuTLS 3.1.x before 3.1.16 and 3.2.x before 3.2.6 allows remote servers to cause a denial of service (memory corruption) via a response with more than four DANE entries. NOTE: this issue is due to an incomplete fix for CVE-2013-4466. | ||||
CVE-2013-4466 | 1 Gnu | 1 Gnutls | 2024-09-16 | N/A |
Buffer overflow in the dane_query_tlsa function in the DANE library (libdane) in GnuTLS 3.1.x before 3.1.15 and 3.2.x before 3.2.5 allows remote servers to cause a denial of service (memory corruption) via a response with more than four DANE entries. | ||||
CVE-2024-0567 | 5 Debian, Fedoraproject, Gnu and 2 more | 9 Debian Linux, Fedora, Gnutls and 6 more | 2024-09-16 | 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 | 2024-09-16 | 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 | 2024-09-16 | 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-2004-2531 | 1 Gnu | 1 Gnutls | 2024-08-08 | 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 | 2024-08-07 | 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-2006-7239 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2024-08-07 | N/A |
The _gnutls_x509_oid2mac_algorithm function in lib/gnutls_algorithms.c in GnuTLS before 1.4.2 allows remote attackers to cause a denial of service (crash) via a crafted X.509 certificate that uses a hash algorithm that is not supported by GnuTLS, which triggers a NULL pointer dereference. | ||||
CVE-2006-4790 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2024-08-07 | 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-2008-4989 | 7 Canonical, Debian, Fedoraproject and 4 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2024-08-07 | 5.9 Medium |
The _gnutls_x509_verify_certificate function in lib/x509/verify.c in libgnutls in GnuTLS before 2.6.1 trusts certificate chains in which the last certificate is an arbitrary trusted, self-signed certificate, which allows man-in-the-middle attackers to insert a spoofed certificate for any Distinguished Name (DN). | ||||
CVE-2008-2377 | 1 Gnu | 1 Gnutls | 2024-08-07 | N/A |
Use-after-free vulnerability in the _gnutls_handshake_hash_buffers_clear function in lib/gnutls_handshake.c in libgnutls in GnuTLS 2.3.5 through 2.4.0 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via TLS transmission of data that is improperly used when the peer calls gnutls_handshake within a normal session, leading to attempted access to a deallocated libgcrypt handle. | ||||
CVE-2008-1948 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2024-08-07 | N/A |
The _gnutls_server_name_recv_params function in lib/ext_server_name.c in libgnutls in gnutls-serv in GnuTLS before 2.2.4 does not properly calculate the number of Server Names in a TLS 1.0 Client Hello message during extension handling, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a zero value for the length of Server Names, which leads to a buffer overflow in session resumption data in the pack_security_parameters function, aka GNUTLS-SA-2008-1-1. | ||||
CVE-2008-1949 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2024-08-07 | N/A |
The _gnutls_recv_client_kx_message function in lib/gnutls_kx.c in libgnutls in gnutls-serv in GnuTLS before 2.2.4 continues to process Client Hello messages within a TLS message after one has already been processed, which allows remote attackers to cause a denial of service (NULL dereference and crash) via a TLS message containing multiple Client Hello messages, aka GNUTLS-SA-2008-1-2. | ||||
CVE-2008-1950 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2024-08-07 | 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-2009-5138 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2024-08-07 | N/A |
GnuTLS before 2.7.6, when the GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT flag is not enabled, treats version 1 X.509 certificates as intermediate CAs, which allows remote attackers to bypass intended restrictions by leveraging a X.509 V1 certificate from a trusted CA to issue new certificates, a different vulnerability than CVE-2014-1959. | ||||
CVE-2009-3555 | 9 Apache, Canonical, Debian and 6 more | 15 Http Server, Ubuntu Linux, Debian Linux and 12 more | 2024-08-07 | N/A |
The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a "plaintext injection" attack, aka the "Project Mogul" issue. | ||||
CVE-2009-2730 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2024-08-07 | 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-2009-2409 | 4 Gnu, Mozilla, Openssl and 1 more | 8 Gnutls, Firefox, Nss and 5 more | 2024-08-07 | 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-2009-1416 | 1 Gnu | 1 Gnutls | 2024-08-07 | N/A |
lib/gnutls_pk.c in libgnutls in GnuTLS 2.5.0 through 2.6.5 generates RSA keys stored in DSA structures, instead of the intended DSA keys, which might allow remote attackers to spoof signatures on certificates or have unspecified other impact by leveraging an invalid DSA key. | ||||
CVE-2009-1417 | 1 Gnu | 1 Gnutls | 2024-08-07 | N/A |
gnutls-cli in GnuTLS before 2.6.6 does not verify the activation and expiration times of X.509 certificates, which allows remote attackers to successfully present a certificate that is (1) not yet valid or (2) no longer valid, related to lack of time checks in the _gnutls_x509_verify_certificate function in lib/x509/verify.c in libgnutls_x509, as used by (a) Exim, (b) OpenLDAP, and (c) libsoup. |
