CVSS: 5.0EPSS: 65%CPEs: 26EXPL: 0CVE-2014-3571 – openssl: DTLS segmentation fault in dtls1_get_record
https://notcve.org/view.php?id=CVE-2014-3571
OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted DTLS message that is processed with a different read operation for the handshake header than for the handshake body, related to the dtls1_get_record function in d1_pkt.c and the ssl3_read_n function in s3_pkt.c. OpenSSL anterior a 0.9.8zd, 1.0.0 anterior a 1.0.0p, y 1.0.1 anterior a 1.0.1k permite a atacantes remotos causar una denegación de servicio (referencia a puntero nulo y caída de la aplicación) a través de un mensaje DTLS manipulado que se procesa con un operación diferente de lectura para la cabecera de negociación que la del cuerpo de la negociación, relacionado con la función dtls1_get_record en d1_pkt.c y la función ssl3_read_n en s3_pkt.c. A NULL pointer dereference flaw was found in the DTLS implementation of OpenSSL. A remote attacker could send a specially crafted DTLS message, which would cause an OpenSSL server to crash. • http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://lists.fedoraproject.org/pipermail/package-announce/2015-January/147938.html http://lists.fedoraproject.org/pipermail/package-announce/2015-January/148363.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 •

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 •
CVSS: 7.1EPSS: 91%CPEs: 34EXPL: 0CVE-2014-3567 – openssl: Invalid TLS/SSL session tickets could cause memory leak leading to server crash
https://notcve.org/view.php?id=CVE-2014-3567
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 •
CVSS: 5.0EPSS: 97%CPEs: 147EXPL: 1CVE-2014-3566 – SSL/TLS: Padding Oracle On Downgraded Legacy Encryption attack
https://notcve.org/view.php?id=CVE-2014-3566
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') •

Multiple buffer overflows in crypto/srp/srp_lib.c in the SRP implementation in OpenSSL 1.0.1 before 1.0.1i allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via an invalid SRP (1) g, (2) A, or (3) B parameter. Múltiples desbordamientos de buffer en crypto/srp/srp_lib.c en la implementación SRP en OpenSSL 1.0.1 anterior a 1.0.1i permiten a atacantes remotos causar una denegación de servicio (caída de aplicación) o posiblemente tener otro impacto no especificado a través de un parámetro SRP (1) g, (2) A, o (3) B inválido. • 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://lists.opensuse.org/opensuse-updates/2014-08/msg00036.html http://marc.info/?l=bugtraq&m=142660345230545&w=2 http://secunia.com/advisories/59700 http://secunia.com/advisories/59710 http://secunia.com/advisories/59756 http://secunia.com/advisories/60022 http://secunia.com/advisories/60221 http://secunia.com/advisories/60493 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
