      "value": "jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.0.0 until 2.18.8, 2.21.4, and 3.1.4, JDKFromStringDeserializer constructed InetSocketAddress with new InetSocketAddress(host, port), which performs eager DNS name resolution for hostname inputs at deserialization time. An application that binds untrusted JSON into a type containing an InetSocketAddress field issues an attacker-chosen DNS query during readValue, before any application-level validation or connect logic. The fix uses InetSocketAddress.createUnresolved(host, port), deferring DNS to an explicit connect. This vulnerability is fixed in 2.18.8, 2.21.4, and 3.1.4."

      "value": "jackson-databind contiene la funcionalidad de enlace de datos de propósito general y el modelo de árbol para Jackson Data Processor. Desde 2.0.0 hasta 2.18.8, 2.21.4 y 3.1.4, JDKFromStringDeserializer construía InetSocketAddress con new InetSocketAddress(host, puerto), lo que realizaba una resolución de nombres DNS anticipada para las entradas de nombre de host en el momento de la deserialización. Una aplicación que enlaza JSON no confiable a un tipo que contiene un campo InetSocketAddress emite una consulta DNS elegida por el atacante durante readValue, antes de cualquier validación a nivel de aplicación o lógica de conexión. La solución utiliza InetSocketAddress.createUnresolved(host, puerto), aplazando la resolución DNS a una conexión explícita. Esta vulnerabilidad se corrige en 2.18.8, 2.21.4 y 3.1.4."
