Race condition in the ssl3_get_new_session_ticket function in ssl/s3_clnt.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b, when used for a multi-threaded client, allows remote attackers to cause a denial of service (double free and application crash) or possibly have unspecified other impact by providing a NewSessionTicket during an attempt to reuse a ticket that had been obtained earlier. Condición de carrera en la función ssl3_get_new_session_ticket en ssl/s3_clnt.c en OpenSSL anterior a 0.9.8zg, 1.0.0 anterior a 1.0.0s, 1.0.1 anterior a 1.0.1n, y 1.0.2 anterior a 1.0.2b, cuando utilizado para un cliente multi-hilo, permite a atacantes remotos causar una denegación de servicio (liberación doble y caída de aplicación) o posiblemente tener otro impacto no especificado mediante la provisión de un NewSessionTicket durante un intento de reutilizar un ticket que se había conseguido anteriormente. A race condition was found in the session handling code of OpenSSL. This issue could possibly cause a multi-threaded TLS/SSL client using OpenSSL to double free session ticket data and crash. • http://fortiguard.com/advisory/openssl-vulnerabilities-june-2015 http://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2015-008.txt.asc http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10694 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10733 http://lists.apple.com/archives/security-announce/2015/Aug/msg00001.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160436.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160647.html http& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

The ASN1_TYPE_cmp function in crypto/asn1/a_type.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not properly perform boolean-type comparisons, which allows remote attackers to cause a denial of service (invalid read operation and application crash) via a crafted X.509 certificate to an endpoint that uses the certificate-verification feature. La función ASN1_TYPE_cmp en crypto/asn1/a_type.c en OpenSSL anterior a 0.9.8zf, 1.0.0 anterior a 1.0.0r, 1.0.1 anterior a 1.0.1m, y 1.0.2 anterior a 1.0.2a no realiza correctamente las comparaciones tipo boolean, lo que permite a atacantes remotos causar una denegación de servicio (operación de lectura inválida y caída de aplicación) a través de un certificado X.509 manipulado en un endpoint que utiliza la característica de verificación de certificados. An invalid pointer use flaw was found in OpenSSL's ASN1_TYPE_cmp() function. A remote attacker could crash a TLS/SSL client or server using OpenSSL via a specially crafted X.509 certificate when the attacker-supplied certificate was verified by the application. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10680 http://lists.apple.com/archives/security-announce/2015/Jun/msg00002.html http://lists.apple.com/archives/security-announce/2015/Sep/msg00001.html http://lists.apple.com/archives/security-announce/2015/Sep/msg00008.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152733.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152734.html http://lists.fedoraproject.org/pipermail/package-announce/2015-Ma • CWE-17: DEPRECATED: Code CWE-125: Out-of-bounds Read •

The ASN1_item_ex_d2i function in crypto/asn1/tasn_dec.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not reinitialize CHOICE and ADB data structures, which might allow attackers to cause a denial of service (invalid write operation and memory corruption) by leveraging an application that relies on ASN.1 structure reuse. La función ASN1_item_ex_d2i en crypto/asn1/tasn_dec.c en OpenSSL anterior a 0.9.8zf, 1.0.0 anterior a 1.0.0r, 1.0.1 anterior a 1.0.1m, y 1.0.2 anterior a 1.0.2a no reinicializa estructuras de datos CHOICE y ADB, lo que podría permitir a atacantes causar una denegación de servicio (operación de escritura inválida y corrupción de memoria) mediante el aprovechamiento de una aplicación que depende del reuso de estructuras ASN.1. An out-of-bounds write flaw was found in the way OpenSSL reused certain ASN.1 structures. A remote attacker could possibly use a specially crafted ASN.1 structure that, when parsed by an application, would cause that application to crash. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10680 http://lists.apple.com/archives/security-announce/2015/Jun/msg00002.html http://lists.apple.com/archives/security-announce/2015/Sep/msg00001.html http://lists.apple.com/archives/security-announce/2015/Sep/msg00008.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152733.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152734.html http://lists.fedoraproject.org/pipermail/package-announce/2015-Ma • CWE-17: DEPRECATED: Code CWE-787: Out-of-bounds Write •

A NULL pointer dereference flaw was found in OpenSSL's X.509 certificate handling implementation. A specially crafted X.509 certificate could cause an application using OpenSSL to crash if the application attempted to convert the certificate to a certificate request. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10680 http://lists.apple.com/archives/security-announce/2015/Jun/msg00002.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152733.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152734.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152844.html http://lists.fedoraproject.org/pipermail/package-announce/2015-May/156823.html http://lists.fedoraproject.org/pipermail/package-announce/ • CWE-476: NULL Pointer Dereference •

The PKCS#7 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not properly handle a lack of outer ContentInfo, which allows attackers to cause a denial of service (NULL pointer dereference and application crash) by leveraging an application that processes arbitrary PKCS#7 data and providing malformed data with ASN.1 encoding, related to crypto/pkcs7/pk7_doit.c and crypto/pkcs7/pk7_lib.c. La implementación PKCS#7 en OpenSSL anterior a 0.9.8zf, 1.0.0 anterior a 1.0.0r, 1.0.1 anterior a 1.0.1m, y 1.0.2 anterior a 1.0.2a no maneja correctamente la falta de ContentInfo exterior, lo que permite a atacantes causar una denegación de servicio (referencia a puntero nulo y caída de aplicación) mediante el aprovechamiento de una aplicación que procesa datos PKCS#7 arbitrarios y la provisión de datos malformados con una codificación ASN.1, relacionado con crypto/pkcs7/pk7_doit.c y crypto/pkcs7/pk7_lib.c. A NULL pointer dereference was found in the way OpenSSL handled certain PKCS#7 inputs. An attacker able to make an application using OpenSSL verify, decrypt, or parse a specially crafted PKCS#7 input could cause that application to crash. TLS/SSL clients and servers using OpenSSL were not affected by this flaw. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10680 http://lists.apple.com/archives/security-announce/2015/Jun/msg00002.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152733.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152734.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152844.html http://lists.fedoraproject.org/pipermail/package-announce/2015-May/156823.html http://lists.fedoraproject.org/pipermail/package-announce/ • CWE-476: NULL Pointer Dereference •
