The ssl23_get_client_hello function in s23_srvr.c in OpenSSL 0.9.8zc, 1.0.0o, and 1.0.1j does not properly handle attempts to use unsupported protocols, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an unexpected handshake, as demonstrated by an SSLv3 handshake to a no-ssl3 application with certain error handling. NOTE: this issue became relevant after the CVE-2014-3568 fix. La función ssl23_get_client_hello en s23_srvr.c en OpenSSL 0.9.8zc, 1.0.0o y 1.0.1j no maneja adecuadamente los intentos de utilizar protocolos no soportados, lo que permite a atacantes remotos causar una denegación de servicio (referencia a puntero NULL y caída de demonio) a través de un apretón de manos no esperado, según lo demostrado por un apretón de manos SSLv3 a una aplicación no-ssl3 con ciertos manejos de errores. NOTA: este problema se volvió relevante después de la corrección de CVE-2014-3568. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10679 http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2015-01/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00011.html http://marc.info/?l=bugtraq&m=142496179803395&w=2 http://marc.info/?l=bugtraq&m=142496289803847&w=2 http://marc.info/?l=bug •

Memory leak in the tls_decrypt_ticket function in t1_lib.c in OpenSSL before 0.9.8zc, 1.0.0 before 1.0.0o, and 1.0.1 before 1.0.1j allows remote attackers to cause a denial of service (memory consumption) via a crafted session ticket that triggers an integrity-check failure. Fuga de memoria en la función tls_decrypt_ticket en t1_lib.c en OpenSSL anterior a 0.9.8zc, 1.0.0 anterior a 1.0.0o, y 1.0.1 anterior a 1.0.1j permite a atacantes remotos causar una denegación de servicio (consumo de memoria) a través de un ticket de sesión manipulado que provoca un fallo en la comprobación de integridad. A memory leak flaw was found in the way an OpenSSL handled failed session ticket integrity checks. A remote attacker could exhaust all available memory of an SSL/TLS or DTLS server by sending a large number of invalid session tickets to that server. • ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2014-015.txt.asc http://advisories.mageia.org/MGASA-2014-0416.html http://aix.software.ibm.com/aix/efixes/security/openssl_advisory11.asc http://lists.apple.com/archives/security-announce/2015/Jan/msg00003.html http://lists.apple.com/archives/security-announce/2015/Sep/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2014-11/msg00001.html http& • CWE-20: Improper Input Validation CWE-399: Resource Management Errors CWE-401: Missing Release of Memory after Effective Lifetime •

OpenSSL before 0.9.8zc, 1.0.0 before 1.0.0o, and 1.0.1 before 1.0.1j does not properly enforce the no-ssl3 build option, which allows remote attackers to bypass intended access restrictions via an SSL 3.0 handshake, related to s23_clnt.c and s23_srvr.c. OpenSSL anterior a 0.9.8zc, 1.0.0 anterior a 1.0.0o, y 1.0.1 anterior a 1.0.1j no fuerza correctamente la opción build no-ssl3, lo que permite a atacantes remotos evadir las restricciones de acceso a través de una negociación SSL 3.0, relacionado con s23_clnt.c y s23_srvr.c. • ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2014-015.txt.asc http://lists.apple.com/archives/security-announce/2015/Jan/msg00003.html http://lists.apple.com/archives/security-announce/2015/Sep/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2014-11/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2014-11/msg00003.html http://lists.opensuse.org/opensuse-security-announce/20 • CWE-310: Cryptographic Issues •

Memory leak in d1_srtp.c in the DTLS SRTP extension in OpenSSL 1.0.1 before 1.0.1j allows remote attackers to cause a denial of service (memory consumption) via a crafted handshake message. Fuga de memoria en d1_srtp.c en la extensión DTLS SRTP en OpenSSL 1.0.1 anterior a 1.0.1j permite a atacantes remotos causar una denegación de servicio (consumo de memoria) a través de un mensaje de negociación manipulado. A memory leak flaw was found in the way OpenSSL parsed the DTLS Secure Real-time Transport Protocol (SRTP) extension data. A remote attacker could send multiple specially crafted handshake messages to exhaust all available memory of an SSL/TLS or DTLS server. • ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2014-015.txt.asc http://advisories.mageia.org/MGASA-2014-0416.html http://aix.software.ibm.com/aix/efixes/security/openssl_advisory11.asc http://lists.apple.com/archives/security-announce/2015/Sep/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2014-11/msg00001.html http://marc.info/?l=bugtraq&m=142118135300698&w=2 http://marc.info&# • CWE-20: Improper Input Validation CWE-401: Missing Release of Memory after Effective Lifetime •

The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue. El protocolo SSL 3.0, utilizado en OpenSSL hasta 1.0.1i y otros productos, utiliza relleno (padding) CBC no determinístico, lo que facilita a los atacantes man-in-the-middle obtener datos de texto plano a través de un ataque de relleno (padding) oracle, también conocido como el problema "POODLE". A flaw was found in the way SSL 3.0 handled padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining (CBC) mode. This flaw allows a man-in-the-middle (MITM) attacker to decrypt a selected byte of a cipher text in as few as 256 tries if they are able to force a victim application to repeatedly send the same data over newly created SSL 3.0 connections. • https://github.com/mikesplain/CVE-2014-3566-poodle-cookbook ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2014-015.txt.asc http://advisories.mageia.org/MGASA-2014-0416.html http://aix.software.ibm.com/aix/efixes/security/openssl_advisory11.asc http://archives.neohapsis.com/archives/bugtraq/2014-10/0101.html http://archives.neohapsis.com/archives/bugtraq/2014-10/0103.html http://askubuntu.com/questions/537196/how-do-i-patch-workaround-sslv3-poodle-vulnerability-cve-2014-3566 http& • CWE-310: Cryptographic Issues CWE-757: Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade') •
