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 •

The default BKS keystore use an HMAC that is only 16 bits long, which can allow an attacker to compromise the integrity of a BKS keystore. Bouncy Castle release 1.47 changes the BKS format to a format which uses a 160 bit HMAC instead. This applies to any BKS keystore generated prior to BC 1.47. For situations where people need to create the files for legacy reasons a specific keystore type "BKS-V1" was introduced in 1.49. It should be noted that the use of "BKS-V1" is discouraged by the library authors and should only be used where it is otherwise safe to do so, as in where the use of a 16 bit checksum for the file integrity check is not going to cause a security issue in itself. • http://www.securityfocus.com/bid/103453 https://access.redhat.com/errata/RHSA-2018:2927 https://www.bouncycastle.org/releasenotes.html https://www.kb.cert.org/vuls/id/306792 https://www.oracle.com/security-alerts/cpuoct2020.html https://access.redhat.com/security/cve/CVE-2018-5382 https://bugzilla.redhat.com/show_bug.cgi?id=1563749 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-354: Improper Validation of Integrity Check Value •

An attacker submitting facts to the Foreman server containing HTML can cause a stored XSS on certain pages: (1) Facts page, when clicking on the "chart" button and hovering over the chart; (2) Trends page, when checking the graph for a trend based on a such fact; (3) Statistics page, for facts that are aggregated on this page. Un atacante que envíe hechos que contienen HTML al servidor Foreman puede provocar Cross-Site Scripting (XSS) persistente en ciertas páginas: (1) La página Facts, al hacer clic en el botón "chart" y desplazándose sobre el gráfico; (2) la página Trends, al comprobar el gráfico para una tendencia basada en un hecho; (3) la página Statistics, para los hechos que se agregan en esta página. • http://projects.theforeman.org/issues/21519 https://access.redhat.com/errata/RHSA-2018:2927 https://github.com/theforeman/foreman/pull/4967 https://access.redhat.com/security/cve/CVE-2017-15100 https://bugzilla.redhat.com/show_bug.cgi?id=1508551 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

A deserialization flaw was discovered in the jackson-databind in versions before 2.8.10 and 2.9.1, which could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper. This issue extends the previous flaw CVE-2017-7525 by blacklisting more classes that could be used maliciously. Se ha descubierto un error de deserialización en jackson-databind, en versiones anteriores a la 2.8.10 y a la 2.9.1, que podría permitir que un usuario no autenticado ejecute código enviando las entradas maliciosamente manipuladas al método readValue de ObjectMapper. Este problema amplía el error previo de CVE-2017-7525 metiendo en la lista negra más clases que podrían emplearse de forma maliciosa.

In Hibernate Validator 5.2.x before 5.2.5 final, 5.3.x, and 5.4.x, it was found that when the security manager's reflective permissions, which allows it to access the private members of the class, are granted to Hibernate Validator, a potential privilege escalation can occur. By allowing the calling code to access those private members without the permission an attacker may be able to validate an invalid instance and access the private member value via ConstraintViolation#getInvalidValue(). En Hibernate Validator 5.2.x anteriores a 5.2.5 final, 5.3.x y 5.4.x, se ha detectado que cuando los permisos reflectivos del gestor de seguridad, el cual accede a los miembros privados de la clase, se conceden a Hibernate Validator, podría ocurrir un escalado de privilegios. Permitiendo que el código de llamada acceda a esos miembros privados sin ningún permiso, el atacante podría validar una instancia no válida y acceder al valor del miembro privado mediante ConstraintViolation#getInvalidValue().
