CVSS: 9.8EPSS: 87%CPEs: 174EXPL: 1CVE-2017-5645 – log4j: Socket receiver deserialization vulnerability
https://notcve.org/view.php?id=CVE-2017-5645
In Apache Log4j 2.x before 2.8.2, when using the TCP socket server or UDP socket server to receive serialized log events from another application, a specially crafted binary payload can be sent that, when deserialized, can execute arbitrary code. En Apache Log4j 2.x en versiones anteriores a 2.8.2, cuando se utiliza el servidor de socket TCP o el servidor de socket UDP para recibir sucesos de registro serializados de otra aplicación, puede enviarse una carga binaria especialmente diseñada que, cuando se deserializa, puede ejecutar código arbitrario. It was found that when using remote logging with log4j socket server the log4j server would deserialize any log event received via TCP or UDP. An attacker could use this flaw to send a specially crafted log event that, during deserialization, would execute arbitrary code in the context of the logger application. • https://github.com/pimps/CVE-2017-5645 http://www.openwall.com/lists/oss-security/2019/12/19/2 http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/97702 http://www.securitytracker.com/id/1040200 http://www.securit • CWE-502: Deserialization of Untrusted Data •
CVSS: 7.5EPSS: 52%CPEs: 87EXPL: 1CVE-2016-8610 – SSL/TLS: Malformed plain-text ALERT packets could cause remote DoS
https://notcve.org/view.php?id=CVE-2016-8610
A denial of service flaw was found in OpenSSL 0.9.8, 1.0.1, 1.0.2 through 1.0.2h, and 1.1.0 in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an excessive amount of CPU and fail to accept connections from other clients. Se ha encontrado un fallo de denegación de servicio en OpenSSL en las versiones 0.9.8, 1.0.1, 1.0.2 hasta la 1.0.2h y la 1.1.0 en la forma en la que el protocolo TLS/SSL definió el procesamiento de paquetes ALERT durante una negociación de conexión. Un atacante remoto podría emplear este fallo para hacer que un servidor TLS/SSL consuma una cantidad excesiva de recursos de CPU y fracase a la hora de aceptar conexiones de otros clientes. A denial of service flaw was found in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. • https://github.com/cujanovic/CVE-2016-8610-PoC http://rhn.redhat.com/errata/RHSA-2017-0286.html http://rhn.redhat.com/errata/RHSA-2017-0574.html http://rhn.redhat.com/errata/RHSA-2017-1415.html http://rhn.redhat.com/errata/RHSA-2017-1659.html http://seclists.org/oss-sec/2016/q4/224 http://www.securityfocus.com/bid/93841 http://www.securitytracker.com/id/1037084 https://access.redhat.com/errata/RHSA-2017:1413 https://access.redhat.com/errata/RHSA-2017:1414 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.5EPSS: 95%CPEs: 18EXPL: 2CVE-2017-3730 – Bad (EC)DHE parameters cause a client crash
https://notcve.org/view.php?id=CVE-2017-3730
In OpenSSL 1.1.0 before 1.1.0d, if a malicious server supplies bad parameters for a DHE or ECDHE key exchange then this can result in the client attempting to dereference a NULL pointer leading to a client crash. This could be exploited in a Denial of Service attack. En OpenSSL versión 1.1.0 anterior a 1.1.0d, si un servidor malicioso suministra parámetros incorrectos para un intercambio de claves DHE o ECDHE, entonces esto puede resultar en que el cliente intente desreferenciar un puntero NULL que conduce a un bloqueo del cliente. Esto podría ser explotado en un ataque de denegación de servicio. • https://www.exploit-db.com/exploits/41192 https://github.com/guidovranken/CVE-2017-3730 http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/95812 http://www.securitytracker.com/id/1037717 https://github.com/openssl/openssl/commit/efbe126e3ebb9123ac9d058aa2bb044261342aaa https://security.gentoo.org/glsa/201702-07 https://support.hpe.com/hpsc/doc/public/display?docLocale=en • CWE-476: NULL Pointer Dereference •

The X509_verify_cert function in crypto/x509/x509_vfy.c in OpenSSL 1.0.1n, 1.0.1o, 1.0.2b, and 1.0.2c does not properly process X.509 Basic Constraints cA values during identification of alternative certificate chains, which allows remote attackers to spoof a Certification Authority role and trigger unintended certificate verifications via a valid leaf certificate. La función de verificación de certificado X509 en crypto/x509/x509_vfy.c en OpenSSL 1.0.1n, 1.0.1o, 1.0.2b, y 1.0.2c no procesa correctamente los valores cA de restricción básica del X.509 durante la identificación de cadenas de certificado alternativo, lo que permite a atacantes remotos suplantar una función de autoridad de certificación y propiciar verificaciones de certificado involuntarias a través de un leaf certificate válido. • https://www.exploit-db.com/exploits/38640 http://fortiguard.com/advisory/2015-07-09-cve-2015-1793-openssl-alternative-chains-certificate-forgery http://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2015-008.txt.asc http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10694 http://lists.fedoraproject.org/pipermail/package-announce/2015-July/161747.html http://lists.fedoraproject.org/pipermail/package-announce/2015-July/161782.html http://marc.info/?l=bugtraq&m=143880121627664&w=2 http • CWE-254: 7PK - Security Features CWE-754: Improper Check for Unusual or Exceptional Conditions •
