CVSS: 5.8EPSS: 2%CPEs: 25EXPL: 0CVE-2013-6450 – openssl: crash in DTLS renegotiation after packet loss
https://notcve.org/view.php?id=CVE-2013-6450
The DTLS retransmission implementation in OpenSSL 1.0.0 before 1.0.0l and 1.0.1 before 1.0.1f does not properly maintain data structures for digest and encryption contexts, which might allow man-in-the-middle attackers to trigger the use of a different context and cause a denial of service (application crash) by interfering with packet delivery, related to ssl/d1_both.c and ssl/t1_enc.c. La implementación de retransmisión DTLS en OpenSSL través 0.9.8y y 1.x través 1.0.1e no mantiene adecuadamente las estructuras de datos para sumarios (hashes) y contextos de cifrado, lo que podría permitir a atacantes man-in-the-middle para activar el uso de un contexto diferente e interferir con la entrega de paquetes, relacionado con ssl/d1_both.c y ssl/t1_enc.c. • http://git.openssl.org/gitweb/?p=openssl.git%3Ba=commit%3Bh=34628967f1e65dc8f34e000f0f5518e21afbfc7b http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136470.html http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136473.html http://lists.opensuse.org/opensuse-updates/2014-01/msg00031.html http://lists.opensuse.org/opensuse-updates/2014-01/msg00032.html http://rhn.redhat.com/errata/RHSA-2014-0015.html http://seclists.org/fulldisclosure/2014/Dec/23 http://security. • CWE-310: Cryptographic Issues •

https://notcve.org/view.php?id=CVE-2013-6449
The ssl_get_algorithm2 function in ssl/s3_lib.c in OpenSSL before 1.0.2 obtains a certain version number from an incorrect data structure, which allows remote attackers to cause a denial of service (daemon crash) via crafted traffic from a TLS 1.2 client. La función ssl_get_algorithm2 en ssl/s3_lib.c en OpenSSL anterior a v1.0.2 obtiene un cierto número de versión de una estructura de datos incorrectos, lo que permite a atacantes remotos provocar una denegación de servicio (caída del demonio) a través de tráfico de red de un cliente TLS v1.2. • http://git.openssl.org/gitweb/?p=openssl.git%3Ba=commit%3Bh=ca989269a2876bae79393bd54c3e72d49975fc75 http://lists.fedoraproject.org/pipermail/package-announce/2013-December/124833.html http://lists.fedoraproject.org/pipermail/package-announce/2013-December/124854.html http://lists.fedoraproject.org/pipermail/package-announce/2013-December/124858.html http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136470.html http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136473.html http://lists • CWE-310: Cryptographic Issues •

OpenSSL before 0.9.8y, 1.0.0 before 1.0.0k, and 1.0.1 before 1.0.1d does not properly perform signature verification for OCSP responses, which allows remote OCSP servers to cause a denial of service (NULL pointer dereference and application crash) via an invalid key. OpenSSL antes de v0.9.8y, v1.0.0 antes de v1.0.0k y v1.0.1 antes de v1.0.1d no realizar correctamente la verificación de firmas para las respuestas OCSP, permite a atacantes remotos provocar una denegación de servicio (desreferencia puntero NULL y caída de la aplicación) a través de una tecla no válida. • http://git.openssl.org/gitweb/?p=openssl.git%3Ba=commit%3Bh=62e4506a7d4cec1c8e1ff687f6b220f6a62a57c7 http://git.openssl.org/gitweb/?p=openssl.git%3Ba=commit%3Bh=66e8211c0b1347970096e04b18aa52567c325200 http://git.openssl.org/gitweb/?p=openssl.git%3Ba=commit%3Bh=ebc71865f0506a293242bd4aec97cdc7a8ef24b0 http://lists.apple.com/archives/security-announce/2013/Sep/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00011.html http: • CWE-310: Cryptographic Issues •

https://notcve.org/view.php?id=CVE-2013-0169
The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0 and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and other products, do not properly consider timing side-channel attacks on a MAC check requirement during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, aka the "Lucky Thirteen" issue. El protocolo TLS v1.1 y v1.2 y el protocolo DTLS v1.0 y v1.2, tal como se utiliza en OpenSSL, OpenJDK, PolarSSL, y otros productos, no considera adecuadamente ataques a un requisito de verificación MAC durante el proceso de relleno CBC malformado, lo que permite a atacantes remotos para realizar ataques distintivos y los ataques de recuperación de texto plano través del análisis estadístico de los datos de tiempo de los paquetes hechos a mano, también conocido como el "Lucky Thirteen" de emisión. • http://blog.fuseyism.com/index.php/2013/02/20/security-icedtea-2-1-6-2-2-6-2-3-7-for-openjdk-7-released http://lists.apple.com/archives/security-announce/2013/Sep/msg00002.html http://lists.fedoraproject.org/pipermail/package-announce/2013-April/101366.html http://lists.opensuse.org/opensuse-security-announce/2013-02/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2013-03/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2013-03/msg00002.html http:/&#x • CWE-310: Cryptographic Issues •
