CVSS: 7.5EPSS: 1%CPEs: 165EXPL: 2CVE-2012-1663 – GnuTLS libgnutls - Double-Free Certificate List Parsing Remote Denial of Service
https://notcve.org/view.php?id=CVE-2012-1663
Double free vulnerability in libgnutls in GnuTLS before 3.0.14 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted certificate list. Vulnerabilidad de doble liberación en libgnutls en GnuTLS antes de 3.0.14 permite a atacantes remotos causar una denegación de servicio (caída de aplicación) o posiblemente tener un impacto no especificado a través de una lista de certificados modificados. • https://www.exploit-db.com/exploits/24865 http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/5866 http://www.exploit-db.com/exploits/24865 https://exchange.xforce.ibmcloud.com/vulnerabilities/74099 • CWE-399: Resource Management Errors •

https://notcve.org/view.php?id=CVE-2012-0390
The DTLS implementation in GnuTLS 3.0.10 and earlier executes certain error-handling code only if there is a specific relationship between a padding length and the ciphertext size, which makes it easier for remote attackers to recover partial plaintext via a timing side-channel attack, a related issue to CVE-2011-4108. La implementación DTLS en GnuTLS v3.0.10 y anteriores ejecuta codigo de gestion de errores sólo si existe una relación específica entre la longitud de relleno y el tamaño del texto cifrado, lo que facilita a los atacantes remotos a la hora de recuperar parte del texto a través de un ataque de temporizacion en canal fisico. Se trata deproblema relacionado con CVE-2011-4108. • http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00001.html http://secunia.com/advisories/57260 http://www.isg.rhul.ac.uk/~kp/dtls.pdf • CWE-310: Cryptographic Issues •

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. El protocolo TLS y el protocolo SSL v3.0 y posiblemente versiones anteriores, tal y como se usa en Microsoft Internet Information Services (IIS) v7.0, mod_ssl en el servidor HTTP Apache v2.2.14 y anteriores, OpenSSL antes de v0.9.8l, GnuTLS v2.8.5 y anteriores, Mozilla Network Security Services (NSS) v3.12.4 y anteriores, y otros productos, no asocia apropiadamente la renegociación del Handshake SSL en una conexión existente, lo que permite ataques man-in-the-middle en los que el atacante inserta datos en sesiones HTTPS, y posiblemente otro tipo de sesiones protegidas por SSL o TLS, enviando una petición de autenticación que es procesada retroactivamente por un servidor en un contexto post-renegociación. Se trata de un ataque de "inyección de texto plano", también conocido como el problema del "Proyecto Mogul". • https://www.exploit-db.com/exploits/10071 https://www.exploit-db.com/exploits/10579 http://archives.neohapsis.com/archives/bugtraq/2013-11/0120.html http://blog.g-sec.lu/2009/11/tls-sslv3-renegotiation-vulnerability.html http://blogs.iss.net/archive/sslmitmiscsrf.html http://blogs.sun.com/security/entry/vulnerability_in_tls_protocol_during http://clicky.me/tlsvuln http://extendedsubset.com/?p=8 http://extendedsubset.com/Renegotiating_TLS.pdf http://h20000.www2.hp.com/bizsuppo • CWE-295: Improper Certificate Validation CWE-300: Channel Accessible by Non-Endpoint •

https://notcve.org/view.php?id=CVE-2009-2730
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. libgnutls en GnuTLS versiones anteriores a v2.8.2 no gestiona adecuadamente un carácter '\0' en el nombre de dominio en los campos de identificación (1) Common Name (CN) o (2) Subject Alternative Name (SAN) de un certificado X.509, permitiendo que atacantes "hombre en el medio" (man-in-the-middle) suplanten servidores SSL de su elección mediante un certificado modificado que ha sido proporcionado por una Autoridad de Certificación legítima. • http://article.gmane.org/gmane.network.gnutls.general/1733 http://lists.opensuse.org/opensuse-security-announce/2009-09/msg00001.html http://secunia.com/advisories/36266 http://secunia.com/advisories/36496 http://www.openwall.com/lists/oss-security/2009/08/14/6 http://www.redhat.com/support/errata/RHSA-2009-1232.html http://www.securityfocus.com/archive/1/507985/100/0/threaded http://www.securitytracker.com/id?1022777 http://www.vmware.com/security/advisories/VMSA-2009-0016. • CWE-310: Cryptographic Issues •

https://notcve.org/view.php?id=CVE-2009-2409
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. La librería Network Security Services (NSS) en versiones anteriores a 3.12.3, como se utiliza en Firefox; GnuTLS en versiones anteriores a 2.6.4 y 2.7.4; OpenSSL 0.9.8 hasta la versión 0.9.8k; y otros productos que soportan MD2 con certificados X.509, lo que podrían permitir a atacantes remotos falsificar certificados usando defectos de diseño de MD2 para generar una colisión de hash en menos que tiempo que con fuerza bruta. NOTA: el alcance de este problema está actualmente limitado porque la cantidad de computación requerida es todavía grande. • http://java.sun.com/j2se/1.5.0/ReleaseNotes.html http://java.sun.com/javase/6/webnotes/6u17.html http://lists.apple.com/archives/security-announce/2009/Nov/msg00000.html http://secunia.com/advisories/36139 http://secunia.com/advisories/36157 http://secunia.com/advisories/36434 http://secunia.com/advisories/36669 http://secunia.com/advisories/36739 http://secunia.com/advisories/37386 http://secunia.com/advisories/42467 http://security.gentoo.org/glsa/glsa-200911-02.x • CWE-310: Cryptographic Issues •
