CVSS: 4.3EPSS: 96%CPEs: 16EXPL: 0CVE-2014-0221 – openssl: DoS when sending invalid DTLS handshake
https://notcve.org/view.php?id=CVE-2014-0221
The dtls1_get_message_fragment function in d1_both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h allows remote attackers to cause a denial of service (recursion and client crash) via a DTLS hello message in an invalid DTLS handshake. La función dtls1_get_message_fragment en d1_both.c en OpenSSL anterior a 0.9.8za, 1.0.0 anterior a 1.0.0m y 1.0.1 anterior a 1.0.1h permite a atacantes remotos causar una denegación de servicio (recursión y caída de cliente) a través de un mensaje DTLS hello en una negociación DTLS inválida. A denial of service flaw was found in the way OpenSSL handled certain DTLS ServerHello requests. A specially crafted DTLS handshake packet could cause a DTLS client using OpenSSL to crash. • http://aix.software.ibm.com/aix/efixes/security/openssl_advisory9.asc http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10629 http://linux.oracle.com/errata/ELSA-2014-1053.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.opensuse.org/opensuse-security-announce/2015-04/msg00016.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00011.html http: • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.5EPSS: 96%CPEs: 8EXPL: 1CVE-2014-0195 – OpenSSL DTLS Fragment Out-Of-Bounds Write Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2014-0195
The dtls1_reassemble_fragment function in d1_both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly validate fragment lengths in DTLS ClientHello messages, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) via a long non-initial fragment. La función dtls1_reassemble_fragment en d1_both.c en OpenSSL anterior a 0.9.8za, 1.0.0 anterior a 1.0.0m y 1.0.1 anterior a 1.0.1h no valida debidamente longitudes de fragmentos en mensajes DTLS ClientHello, lo que permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (desbordamiento de buffer y caída de aplicación) a través de un fragmento no inicial largo. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of OpenSSL. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of DTLS packets. The issue lies in the assumption that all fragments specify the same message size. • https://github.com/ricedu/CVE-2014-0195 http://aix.software.ibm.com/aix/efixes/security/openssl_advisory9.asc http://h30499.www3.hp.com/t5/HP-Security-Research-Blog/Once-Bled-Twice-Shy-OpenSSL-CVE-2014-0195/ba-p/6501048 http://h30499.www3.hp.com/t5/HP-Security-Research-Blog/ZDI-14-173-CVE-2014-0195-OpenSSL-DTLS-Fragment-Out-of-Bounds/ba-p/6501002 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10629 http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

https://notcve.org/view.php?id=CVE-2014-0198
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 •
