Starting in version 2.0.0 and prior to version 2.13.0, a flaw in jackson-core's `JsonLocation._appendSourceDesc` method allows up to 500 bytes of unintended memory content to be included in exception messages. When parsing JSON from a byte array with an offset and length, the exception message incorrectly reads from the beginning of the array instead of the logical payload start. This results in possible information disclosure in systems using pooled or reused buffers, like Netty or Vert.x. This issue was silently fixed in jackson-core version 2.13.0, released on September 30, 2021, via PR #652. All users should upgrade to version 2.13.0 or later. If upgrading is not immediately possible, applications can mitigate the issue by disabling exception message exposure to clients to avoid returning parsing exception messages in HTTP responses and/or disabling source inclusion in exceptions to prevent Jackson from embedding any source content in exception messages, avoiding leakage."}, {"lang": "es", "value": "Jackson-core contiene abstracciones de analizador y generador incrementales (\"streaming\") de bajo nivel que utiliza Jackson Data Processor. A partir de la versi\u00f3n 2.0.0 y anteriores a la 2.13.0, una falla en el m\u00e9todo `JsonLocation._appendSourceDesc` de jackson-core permite incluir hasta 500 bytes de contenido de memoria no deseado en los mensajes de excepci\u00f3n. Al analizar JSON desde una matriz de bytes con un desplazamiento y una longitud, el mensaje de excepci\u00f3n lee incorrectamente desde el principio de la matriz en lugar del inicio l\u00f3gico del payload. Esto puede provocar la divulgaci\u00f3n de informaci\u00f3n en sistemas que utilizan b\u00faferes agrupados o reutilizados, como Netty o Vert.x. Este problema se solucion\u00f3 de forma silenciosa en la versi\u00f3n 2.13.0 de jackson-core, publicada el 30 de septiembre de 2021, mediante la solicitud de registro n.\u00b0 652. Todos los usuarios deben actualizar a la versi\u00f3n 2.13.0 o posterior. Si la actualizaci\u00f3n no es posible de inmediato, las aplicaciones pueden mitigar el problema deshabilitando la exposici\u00f3n de mensajes de excepci\u00f3n a los clientes para evitar devolver mensajes de excepci\u00f3n de an\u00e1lisis en respuestas HTTP y/o deshabilitando la inclusi\u00f3n de fuente en excepciones para evitar que Jackson incorpore cualquier contenido de fuente en los mensajes de excepci\u00f3n, evitando fugas."}], "lastModified": "2025-06-09T16:15:44.947", "sourceIdentifier": "security-advisories@github.com"}
