https://notcve.org/view.php?id=CVE-2011-4577
OpenSSL before 0.9.8s and 1.x before 1.0.0f, when RFC 3779 support is enabled, allows remote attackers to cause a denial of service (assertion failure) via an X.509 certificate containing certificate-extension data associated with (1) IP address blocks or (2) Autonomous System (AS) identifiers. OpenSSL antes de v0.9.8s y v1.x antes de v1.0.0f, cuando el soporte al RFC 3779 está habilitado, permite a atacantes remotos provocar una denegación de servicio (error de aserción) a través de un certificado X.509 que contiene la extensión de certificados de datos asociados con identificados de (1) bloques de direcciones IP o (2) Sistema Autónomo (AS). • http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c03360041 http://lists.apple.com/archives/security-announce/2013/Jun/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2012-November/092905.html http://lists.opensuse.org/opensuse-security-announce/2012-01/msg00017.html http://lists.opensuse.org/opensuse-security-announce/2012-01/msg00018.html http://marc.info/?l=bugtraq&m=132750648501816&w=2 http://marc.info/?l=bugtraq&m=134039053214295&w=2 http://s • CWE-399: Resource Management Errors •

https://notcve.org/view.php?id=CVE-2011-4619
The Server Gated Cryptography (SGC) implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly handle handshake restarts, which allows remote attackers to cause a denial of service (CPU consumption) via unspecified vectors. La implementación del servidor de criptografía SGC en OpenSSL antes de v0.9.8s y en v1.x antes de v1.0.0f no controla correctamente los reinicios de 'handshake' (apretón de manos), lo que permite a atacantes remotos provocar una denegación de servicio a través de vectores no especificados. • http://aix.software.ibm.com/aix/efixes/security/openssl_advisory3.asc http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c03360041 http://lists.apple.com/archives/security-announce/2013/Jun/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2012-November/092905.html http://lists.opensuse.org/opensuse-security-announce/2012-01/msg00017.html http://lists.opensuse.org/opensuse-security-announce/2012-01/msg00018.html http://marc.info/?l=bugtraq&m=132750648501816&w=2 • CWE-399: Resource Management Errors •

https://notcve.org/view.php?id=CVE-2011-4108
The DTLS implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f performs a MAC check only if certain padding is valid, which makes it easier for remote attackers to recover plaintext via a padding oracle attack. La implementación DTLS en OpenSSL antes de v0.9.8s y v1.x antes de v1.0.0f realiza una comprobación de MAC sólo si determinado relleno es válida, lo que facilita a los atacantes remotos a la hora de recuperar texto a través de un ataque de relleno. • http://aix.software.ibm.com/aix/efixes/security/openssl_advisory3.asc http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c03360041 http://lists.apple.com/archives/security-announce/2013/Jun/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2012-November/092905.html http://lists.opensuse.org/opensuse-security-announce/2012-01/msg00017.html http://lists.opensuse.org/opensuse-security-announce/2012-01/msg00018.html http://lists.opensuse.org/opensuse-security-announce/201 • CWE-310: Cryptographic Issues •

https://notcve.org/view.php?id=CVE-2011-1945
The elliptic curve cryptography (ECC) subsystem in OpenSSL 1.0.0d and earlier, when the Elliptic Curve Digital Signature Algorithm (ECDSA) is used for the ECDHE_ECDSA cipher suite, does not properly implement curves over binary fields, which makes it easier for context-dependent attackers to determine private keys via a timing attack and a lattice calculation. El subsistema de criptografía de curva elíptica (ECC) de OpenSSL v1.0.0d y versiones anteriores, cuando el algoritmo de firma digital de la curva elímptica(ECDSA) se utiliza para el conjunto de cifrado ECDHE_ECDSA, no aplica adecuadamente las curvas sobre campos binarios, lo que hace que sea más fácil para el atacantes dependientes del contexto determinar las claves privadas a través de un ataque de oportunidad y un cálculo del entramado (lattice). • http://eprint.iacr.org/2011/232.pdf http://lists.apple.com/archives/security-announce/2013/Jun/msg00000.html http://secunia.com/advisories/44935 http://support.apple.com/kb/HT5784 http://www.debian.org/security/2011/dsa-2309 http://www.kb.cert.org/vuls/id/536044 http://www.kb.cert.org/vuls/id/MAPG-8FENZ3 http://www.mandriva.com/security/advisories?name=MDVSA-2011:136 http://www.mandriva.com/security/advisories?name=MDVSA-2011:137 https://hermes.opensuse.org/m • CWE-310: Cryptographic Issues •

https://notcve.org/view.php?id=CVE-2008-7270
OpenSSL before 0.9.8j, when SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is enabled, does not prevent modification of the ciphersuite in the session cache, which allows remote attackers to force the use of a disabled cipher via vectors involving sniffing network traffic to discover a session identifier, a different vulnerability than CVE-2010-4180. OpenSSL en versiones anteriores a la 0.9.8j, si SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG está activado, no previene la modificación de sus datos en la caché de sesión, lo que permite a atacantes remotos forzar el uso de protocolos de cifrado deshabilitados a través de vectores de ataque que involucran la captura del tráfico de red para descubrir un identificador de sesión. Es una vulnerabilidad distinta a la CVE-2010-4180. • http://cvs.openssl.org/chngview?cn=17489 http://marc.info/?l=bugtraq&m=132077688910227&w=2 http://secunia.com/advisories/42493 http://ubuntu.com/usn/usn-1029-1 http://www.redhat.com/support/errata/RHSA-2010-0977.html http://www.redhat.com/support/errata/RHSA-2010-0978.html http://www.redhat.com/support/errata/RHSA-2011-0896.html http://www.securityfocus.com/archive/1/522176 http://www.securityfocus.com/bid/45254 https://bugzilla.redhat.com/show_bug.cgi?id= • CWE-310: Cryptographic Issues •
