CVE-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 •
