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 •
CVSS: 7.5EPSS: 95%CPEs: 32EXPL: 0CVE-2015-3194 – OpenSSL: Certificate verify crash with missing PSS parameter
https://notcve.org/view.php?id=CVE-2015-3194
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. A remote attacker could possibly use this flaw to crash a TLS/SSL client using OpenSSL, or a TLS/SSL server using OpenSSL if it enabled client authentication. • 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-security-announce/2016-03/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00053.html http://lists.opensuse.org/opensuse-updates/2015-12/msg00070.html http://lists.opensus • CWE-476: NULL Pointer Dereference •
