CVE-2008-1949 1 Gnu 1 Gnutls 2023-11-07 9.3 HIGH 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-2008-1948 1 Gnu 1 Gnutls 2023-11-07 10.0 HIGH 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-2018-10846 5 Canonical, Debian, Fedoraproject and 2 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2023-02-13 1.9 LOW 5.6 MEDIUM
A cache-based side channel in GnuTLS implementation that leads to plain text recovery in cross-VM attack setting was found. An attacker could use a combination of "Just in Time" Prime+probe attack in combination with Lucky-13 attack to recover plain text using crafted packets.
CVE-2018-10845 5 Canonical, Debian, Fedoraproject and 2 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2023-02-13 4.3 MEDIUM 5.9 MEDIUM
It was found that the GnuTLS implementation of HMAC-SHA-384 was vulnerable to a Lucky thirteen style attack. Remote attackers could use this flaw to conduct distinguishing attacks and plain text recovery attacks via statistical analysis of timing data using crafted packets.
CVE-2018-10844 5 Canonical, Debian, Fedoraproject and 2 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2023-02-13 4.3 MEDIUM 5.9 MEDIUM
It was found that the GnuTLS implementation of HMAC-SHA-256 was vulnerable to a Lucky thirteen style attack. Remote attackers could use this flaw to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data using crafted packets.
CVE-2009-3555 8 Apache, Canonical, Debian and 5 more 8 Http Server, Ubuntu Linux, Debian Linux and 5 more 2023-02-13 5.8 MEDIUM 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-2006-7239 1 Gnu 1 Gnutls 2023-02-13 5.0 MEDIUM 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-2014-8155 1 Gnu 1 Gnutls 2023-02-13 4.3 MEDIUM 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-2018-16868 1 Gnu 1 Gnutls 2022-11-30 3.3 LOW 5.6 MEDIUM
A Bleichenbacher type side-channel based padding oracle attack was found in the way gnutls handles verification of RSA decrypted PKCS#1 v1.5 data. An attacker who is able to run process on the same physical core as the victim process, could use this to extract plaintext or in some cases downgrade any TLS connections to a vulnerable server.
CVE-2021-4209 3 Gnu, Netapp, Redhat 6 Gnutls, Active Iq Unified Manager, Hci Bootstrap Os and 3 more 2022-10-27 N/A 6.5 MEDIUM
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-2014-3467 5 Debian, F5, Gnu and 2 more 16 Debian Linux, Arx, Arx Firmware and 13 more 2020-11-16 5.0 MEDIUM 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-2014-3468 5 Debian, F5, Gnu and 2 more 16 Debian Linux, Arx, Arx Firmware and 13 more 2020-11-16 7.5 HIGH 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-2014-3469 4 Debian, Gnu, Redhat and 1 more 14 Debian Linux, Gnutls, Libtasn1 and 11 more 2020-11-16 5.0 MEDIUM N/A
The (1) asn1_read_value_type and (2) asn1_read_value functions in GNU Libtasn1 before 3.6 allows context-dependent attackers to cause a denial of service (NULL pointer dereference and crash) via a NULL value in an ivalue argument.
CVE-2016-4456 1 Gnu 1 Gnutls 2020-06-16 5.0 MEDIUM 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-2015-0294 3 Debian, Gnu, Redhat 3 Debian Linux, Gnutls, Enterprise Linux 2020-01-31 5.0 MEDIUM 7.5 HIGH
GnuTLS before 3.3.13 does not validate that the signature algorithms match when importing a certificate.
CVE-2015-8313 2 Debian, Gnu 2 Debian Linux, Gnutls 2020-01-09 4.3 MEDIUM 5.9 MEDIUM
GnuTLS incorrectly validates the first byte of padding in CBC modes
CVE-2014-8564 4 Canonical, Gnu, Opensuse and 1 more 7 Ubuntu Linux, Gnutls, Opensuse and 4 more 2018-10-30 5.0 MEDIUM 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-2013-4487 2 Gnu, Opensuse 2 Gnutls, Opensuse 2018-10-30 5.0 MEDIUM N/A
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-2017-5336 2 Gnu, Opensuse 2 Gnutls, Leap 2018-10-30 7.5 HIGH 9.8 CRITICAL
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 2 Gnu, Opensuse 2 Gnutls, Leap 2018-10-30 5.0 MEDIUM 7.5 HIGH
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.
