CVSS: 10.0EPSS: 0%CPEs: 1EXPL: 0CVE-2018-1085 – openshift-ansible: Incorrectly quoted values in etcd.conf causes disabling of SSL client certificate authentication
https://notcve.org/view.php?id=CVE-2018-1085
openshift-ansible before versions 3.9.23, 3.7.46 deploys a misconfigured etcd file that causes the SSL client certificate authentication to be disabled. Quotations around the values of ETCD_CLIENT_CERT_AUTH and ETCD_PEER_CLIENT_CERT_AUTH in etcd.conf result in etcd being configured to allow remote users to connect without any authentication if they can access the etcd server bound to the network on the master nodes. An attacker could use this flaw to read and modify all the data about the Openshift cluster in the etcd datastore, potentially adding another compute node, or bringing down the entire cluster. openshift-ansible en versiones anteriores a la 3.9.23 y 3.7.46 implementa un archivo etcd mal configurado que provoca que la autenticación del certificado de cliente SSL se deshabilite. Las comillas en los valores de ETCD_CLIENT_CERT_AUTH y ETCD_PEER_CLIENT_CERT_AUTH en etcd.conf resultan en que etcd se configura para permitir que usuarios remotos se conecten sin autenticación si pueden acceder al servidor etcd enlazado a la red en los nodos maestros. Un atacante puede emplear este error para leer y modificar todos los datos sobre el clúster Openshift en el almacén de datos etcd, añadiendo potencialmente otro nodo de ordenador o haciendo que caiga todo el clúster. • https://access.redhat.com/errata/RHSA-2018:2013 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-1085 https://access.redhat.com/security/cve/CVE-2018-1085 https://bugzilla.redhat.com/show_bug.cgi?id=1557822 • CWE-287: Improper Authentication CWE-592: DEPRECATED: Authentication Bypass Issues •

routing before version 3.10 is vulnerable to an improper input validation of the Openshift Routing configuration which can cause an entire shard to be brought down. A malicious user can use this vulnerability to cause a Denial of Service attack for other users of the router shard. routing en versiones anteriores a la 3.10 es vulnerable a una validación de entradas incorrecta de la configuración de Openshift Routing que puede permitir que una partición entera se caiga. Un usuario malicioso puede emplear esta vulnerabilidad para provocar un ataque de denegación de servicio (DoS) para otros usuarios de la partición del router.

CVSS: 5.9EPSS: 1%CPEs: 42EXPL: 0CVE-2018-10237 – guava: Unbounded memory allocation in AtomicDoubleArray and CompoundOrdering classes allow remote attackers to cause a denial of service
https://notcve.org/view.php?id=CVE-2018-10237
Unbounded memory allocation in Google Guava 11.0 through 24.x before 24.1.1 allows remote attackers to conduct denial of service attacks against servers that depend on this library and deserialize attacker-provided data, because the AtomicDoubleArray class (when serialized with Java serialization) and the CompoundOrdering class (when serialized with GWT serialization) perform eager allocation without appropriate checks on what a client has sent and whether the data size is reasonable. Asignación de memoria sin restringir en Google Guava 11.0 hasta las versiones 24.x anteriores a la 24.1.1 permite que los atacantes remotos realicen ataques de denegación de servicio (DoS) contra servidores que dependen de esta librería y que deserialicen datos proporcionados por dichos atacantes debido a que la clase AtomicDoubleArray (cuando se serializa con serialización Java) y la clase CompoundOrdering (cuando se serializa con serialización GWT) realiza una asignación sin comprobar adecuadamente lo que ha enviado un cliente y si el tamaño de los datos es razonable. A vulnerability was found in Guava where the AtomicDoubleArray and CompoundOrdering classes were found to allocate memory based on size fields sent by the client without validation. A crafted message could cause the server to consume all available memory or crash leading to a denial of service. • http://www.securitytracker.com/id/1041707 https://access.redhat.com/errata/RHSA-2018:2423 https://access.redhat.com/errata/RHSA-2018:2424 https://access.redhat.com/errata/RHSA-2018:2425 https://access.redhat.com/errata/RHSA-2018:2428 https://access.redhat.com/errata/RHSA-2018:2598 https://access.redhat.com/errata/RHSA-2018:2643 https://access.redhat.com/errata/RHSA-2018:2740 https://access.redhat.com/errata/RHSA-2018:2741 https://access.redhat.com/errata/RHSA-2018:274 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-770: Allocation of Resources Without Limits or Throttling •
