https://notcve.org/view.php?id=CVE-2014-3510
The ssl3_send_client_key_exchange function in s3_clnt.c in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1 before 1.0.1i allows remote DTLS servers to cause a denial of service (NULL pointer dereference and client application crash) via a crafted handshake message in conjunction with a (1) anonymous DH or (2) anonymous ECDH ciphersuite. La función ssl3_send_client_key_exchange en s3_clnt.c en OpenSSL 0.9.8 anterior a 0.9.8zb, 1.0.0 anterior a 1.0.0n, y 1.0.1 anterior a 1.0.1i permite a servidores DTLS remotos causar una denegación de servicio (referencia a puntero nulo y caída de la aplicación del cliente) a través de un mensaje de negociación manipulado en conjunto con un suite de cifrado (1) anónimo DH o (2) anónimo ECDH. A NULL pointer dereference flaw was found in the way OpenSSL performed a handshake when using the anonymous Diffie-Hellman (DH) key exchange. A malicious server could cause a DTLS client using OpenSSL to crash if that client had anonymous DH cipher suites enabled. • ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2014-008.txt.asc http://aix.software.ibm.com/aix/efixes/security/openssl_advisory10.asc http://linux.oracle.com/errata/ELSA-2014-1052.html 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/2016-03/msg00011.html http:/& • CWE-476: NULL Pointer Dereference •

OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka the "CCS Injection" vulnerability. OpenSSL anterior a 0.9.8za, 1.0.0 anterior a 1.0.0m y 1.0.1 anterior a 1.0.1h no restringe debidamente el procesamiento de mensajes ChangeCipherSpec, lo que permite a atacantes man-in-the-middle provocar el uso de una clave maestra de longitud cero en ciertas comunicaciones OpenSSL-a-OpenSSL, y como consecuencia secuestrar sesiones u obtener información sensible, a través de una negociación TLS manipulada, también conocido como la vulnerabilidad de 'inyección CCS'. It was found that OpenSSL clients and servers could be forced, via a specially crafted handshake packet, to use weak keying material for communication. A man-in-the-middle attacker could use this flaw to decrypt and modify traffic between a client and a server. • https://github.com/secretnonempty/CVE-2014-0224 https://github.com/iph0n3/CVE-2014-0224 http://aix.software.ibm.com/aix/efixes/security/openssl_advisory9.asc http://ccsinjection.lepidum.co.jp http://dev.mysql.com/doc/relnotes/workbench/en/wb-news-6-1-7.html http://esupport.trendmicro.com/solution/en-US/1103813.aspx http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10629 http://kb.juniper.net/InfoCenter/index?page=content&id=KB29195 http://kb.juniper.net/InfoCenter/ • CWE-326: Inadequate Encryption Strength CWE-841: Improper Enforcement of Behavioral Workflow •

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') •
