The do_ssl3_write function in s3_pkt.c in OpenSSL 1.x through 1.0.1g, when SSL_MODE_RELEASE_BUFFERS is enabled, does not properly manage a buffer pointer during certain recursive calls, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors that trigger an alert condition. La función do_ssl3_write en s3_pkt.c en OpenSSL 1.x hasta 1.0.1g, cuando SSL_MODE_RELEASE_BUFFERS está habilitado, no maneja debidamente un puntero de buffer durante ciertas llamadas recursivas, lo que permite a atacantes remotos causar una denegación de servicio (referencia a puntero nulo y caída de aplicación) a través de vectores que provocan una condición de alerta. • http://advisories.mageia.org/MGASA-2014-0204.html http://aix.software.ibm.com/aix/efixes/security/openssl_advisory9.asc http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10629 http://kb.juniper.net/InfoCenter/index?page=content&id=KB29195 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-security-announce/2015-04/msg00016.html http://lists.opens • CWE-476: NULL Pointer Dereference •

Race condition in the ssl3_read_bytes function in s3_pkt.c in OpenSSL through 1.0.1g, when SSL_MODE_RELEASE_BUFFERS is enabled, allows remote attackers to inject data across sessions or cause a denial of service (use-after-free and parsing error) via an SSL connection in a multithreaded environment. Condición de carrera en la función ssl3_read_bytes en s3_pkt.c en OpenSSL hasta 1.0.1g, cuando SSL_MODE_RELEASE_BUFFERS está habilitado, permite a atacantes remotos inyectar datos a través de sesiones o causar una denegación de servicio (error de uso después de liberación y análisis sintáctico) a través de una conexión SSL en un entorno con múltiples hilos. • http://advisories.mageia.org/MGASA-2014-0187.html http://ftp.openbsd.org/pub/OpenBSD/patches/5.5/common/004_openssl.patch.sig http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10629 http://kb.juniper.net/InfoCenter/index?page=content&id=KB29195 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-security-announce/2015-04/msg00016.html http:/& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

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 •
