The DH_check_pub_key function in crypto/dh/dh_check.c in OpenSSL 1.0.2 before 1.0.2f does not ensure that prime numbers are appropriate for Diffie-Hellman (DH) key exchange, which makes it easier for remote attackers to discover a private DH exponent by making multiple handshakes with a peer that chose an inappropriate number, as demonstrated by a number in an X9.42 file. La función DH_check_pub_key en crypto/dh/dh_check.c en OpenSSL 1.0.2 en versiones anteriores a 1.0.2f no asegura que los número primos son apropiados para el intercambio de clave Diffie-Hellman (DH), lo que hace que sea más fácil para atacantes remotos descubrir el exponente DH privado mediante la realización de múltiples apretones de mano con un par que eligió un número inapropiado, según lo demostrado por un número en un archivo X9.42. • http://intothesymmetry.blogspot.com/2016/01/openssl-key-recovery-attack-on-dh-small.html http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.fedoraproject.org/pipermail/package-announce/2016-January/176373.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00009.html http://www.openssl.org/news/secadv/20160128.txt http://www.oracle.com/technetwork/security-advisory/cpujul2016-2881720.html http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html ht • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 4.3EPSS: 1%CPEs: 65EXPL: 0CVE-2015-3196 – OpenSSL: Race condition handling PSK identify hint
https://notcve.org/view.php?id=CVE-2015-3196
ssl/s3_clnt.c in OpenSSL 1.0.0 before 1.0.0t, 1.0.1 before 1.0.1p, and 1.0.2 before 1.0.2d, when used for a multi-threaded client, writes the PSK identity hint to an incorrect data structure, which allows remote servers to cause a denial of service (race condition and double free) via a crafted ServerKeyExchange message. ssl/s3_clnt.c en OpenSSL 1.0.0 en versiones anteriores a 1.0.0t, 1.0.1 en versiones anteriores a 1.0.1p y 1.0.2 en versiones anteriores a 1.0.2d, cuando es utilizado por un cliente multi hilo, escribe la pista de identidad PSK en una estructura de datos incorrecta, lo que permite a servidores remotos provocar una denegación de servicio (condición de carrera y liberación doble) a través de un mensaje ServerKeyExchange manipulado. A race condition flaw, leading to a double free, was found in the way OpenSSL handled pre-shared key (PSK) identify hints. A remote attacker could use this flaw to crash a multi-threaded SSL/TLS client using OpenSSL. • http://fortiguard.com/advisory/openssl-advisory-december-2015 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10761 http://lists.fedoraproject.org/pipermail/package-announce/2015-December/173801.html http://lists.opensuse.org/opensuse-updates/2015-12/msg00070.html http://lists.opensuse.org/opensuse-updates/2015-12/msg00071.html http://marc.info/?l=bugtraq&m=145382583417444&w=2 http://openssl.org/news/secadv/20151203.txt • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

The Montgomery squaring implementation in crypto/bn/asm/x86_64-mont5.pl in OpenSSL 1.0.2 before 1.0.2e on the x86_64 platform, as used by the BN_mod_exp function, mishandles carry propagation and produces incorrect output, which makes it easier for remote attackers to obtain sensitive private-key information via an attack against use of a (1) Diffie-Hellman (DH) or (2) Diffie-Hellman Ephemeral (DHE) ciphersuite. La implementación de exponenciación al cuadrado de Montgomery en crypto/bn/asm/x86_64-mont5.pl en OpenSSL 1.0.2 en versiones anteriores a 1.0.2e en la plataforma x86_64, como se utiliza por la función BN_mod_exp, no maneja correctamente la propagación de acarreo y produce una salida incorrecta, lo que hace más fácil para atacantes remotos obtener información sensible de las claves privadas a través de un ataque contra el uso de una suite de cifrado (1) Diffie-Hellman (DH) o (2) Diffie-Hellman Ephemeral (DHE). • http://fortiguard.com/advisory/openssl-advisory-december-2015 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10761 http://openssl.org/news/secadv/20151203.txt http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20151204-openssl http://www.fortiguard.com/advisory/openssl-advisory-december-2015 http://www.oracle.com/technetwork/security-advisory/cpuapr2016v3-2985753.html http://www.oracle.com/technetwork/security • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

crypto/rsa/rsa_ameth.c in OpenSSL 1.0.1 before 1.0.1q and 1.0.2 before 1.0.2e allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an RSA PSS ASN.1 signature that lacks a mask generation function parameter. crypto/rsa/rsa_ameth.c en OpenSSL 1.0.1 en versiones anteriores a 1.0.1q y 1.0.2 en versiones anteriores a 1.0.2e permite a atacantes remotos provocar una denegación de servicio (referencia a puntero NULL y caída de aplicación) a través de una firma RSA PSS ASN.1 que carece de un parámetro de función de generación de máscara. A NULL pointer dereference flaw was found in the way OpenSSL verified signatures using the RSA PSS algorithm.
