https://notcve.org/view.php?id=CVE-2014-3468
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. La función asn1_get_bit_der en GNU Libtasn1 anterior a 3.6 no informa debidamente de un error cuando una longitud de bit negativa está identificada, lo que permite a atacantes dependientes de contexto causar acceso fuera de rango a través de datos ASN.1 manipulados. • http://advisories.mageia.org/MGASA-2014-0247.html http://git.savannah.gnu.org/cgit/libtasn1.git/commit/?id=1c3ccb3e040bf13e342ee60bc23b21b97b11923f http://linux.oracle.com/errata/ELSA-2014-0594.html http://linux.oracle.com/errata/ELSA-2014-0596.html http://lists.gnu.org/archive/html/help-libtasn1/2014-05/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2014-06/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2014-06/msg00015.html http://rhn.redhat.com/err • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-131: Incorrect Calculation of Buffer Size •

CVSS: 6.8EPSS: 59%CPEs: 47EXPL: 2CVE-2014-3466 – gnutls: insufficient session id length check in _gnutls_read_server_hello (GNUTLS-SA-2014-3)
https://notcve.org/view.php?id=CVE-2014-3466
Buffer overflow in the read_server_hello function in lib/gnutls_handshake.c in GnuTLS before 3.1.25, 3.2.x before 3.2.15, and 3.3.x before 3.3.4 allows remote servers to cause a denial of service (memory corruption) or possibly execute arbitrary code via a long session id in a ServerHello message. Desbordamiento de buffer en la función read_server_hello en lib/gnutls_handshake.c en GnuTLS anterior a 3.1.25, 3.2.x anterior a 3.2.15 y 3.3.x anterior a 3.3.4 permite a servidores remotos causar una denegación de servicio (consumo de memoria) o posiblemente ejecutar código arbitrario a través de una sesión id larga en un mensaje ServerHello. A flaw was found in the way GnuTLS parsed session IDs from ServerHello messages of the TLS/SSL handshake. A malicious server could use this flaw to send an excessively long session ID value, which would trigger a buffer overflow in a connecting TLS/SSL client application using GnuTLS, causing the client application to crash or, possibly, execute arbitrary code. • http://linux.oracle.com/errata/ELSA-2014-0594.html http://linux.oracle.com/errata/ELSA-2014-0595.html http://lists.opensuse.org/opensuse-security-announce/2014-06/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2014-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2014-06/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2014-06/msg00015.html http://radare.today/technical-analysis-of-the-gnutls-hello-vulnerability http://rhn.redhat.com/e • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2009-5138
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. GnuTLS anterior a 2.7.6, cuando el indicador GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT no está habilitado, trata certificados X.509 de versión 1 como CAs intermedios, lo que permite a atacantes remotos evadir restricciones mediante el aprovechamiento de un certificado X.509 V1 de un CA confiable para emitir certificados nuevos, una vulnerabilidad diferente a CVE-2014-1959. • http://article.gmane.org/gmane.comp.security.oss.general/12223 http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00020.html http://rhn.redhat.com/errata/RHSA-2014-0247.html http://secunia.com/advisories/57254 http://secunia.com/advisories/57260 http://sec • CWE-264: Permissions, Privileges, and Access Controls CWE-295: Improper Certificate Validation •
