CVSS: 5.0EPSS: 62%CPEs: 45EXPL: 0CVE-2015-1792 – OpenSSL: CMS verify infinite loop with unknown hash function
https://notcve.org/view.php?id=CVE-2015-1792
The do_free_upto function in crypto/cms/cms_smime.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 allows remote attackers to cause a denial of service (infinite loop) via vectors that trigger a NULL value of a BIO data structure, as demonstrated by an unrecognized X.660 OID for a hash function. La función do_free_upto en crypto/cms/cms_smime.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 permite a atacantes remotos causar una denegación de servicio (bucle infinito) a través de vectores que provocan un valor nulo de una estructura de datos BIO, tal y como fue demostrado mediante un X.660 OID no reconocido para una función hash. A denial of service flaw was found in the way OpenSSL verified certain signed messages using CMS (Cryptographic Message Syntax). A remote attacker could cause an application using OpenSSL to use excessive amounts of memory by sending a specially crafted message for verification. • 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://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://lists.opensuse.org/opensuse-security-announce/2015-06/msg00023 • CWE-399: Resource Management Errors CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

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') •

https://notcve.org/view.php?id=CVE-2015-1789
The X509_cmp_time function in crypto/x509/x509_vfy.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 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted length field in ASN1_TIME data, as demonstrated by an attack against a server that supports client authentication with a custom verification callback. La función X509_cmp_time en crypto/x509/x509_vfy.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 permite a atacantes remotos causar una denegación de servicio (lectura fuera de rango y caída de aplicación) a través de un campo de longitud manipulado en datos ASN1_TIME, tal y como fue demostrado mediante un ataque sobre un servidor que soporta la autenticación de clientes con una rellamada de verificación personalizada. An out-of-bounds read flaw was found in the X509_cmp_time() function of OpenSSL, which is used to test the expiry dates of SSL/TLS certificates. An attacker could possibly use a specially crafted SSL/TLS certificate or CRL (Certificate Revocation List), which when parsed by an application would cause that application to 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-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
