      "value": "On unix-like systems, the temporary directory is shared between all user. As such, writing to this directory using APIs that do not explicitly set the file/directory permissions can lead to information disclosure. Of note, this does not impact modern MacOS Operating Systems.\n\nThe method File.createTempFile on unix-like systems creates a file with predefined name (so easily identifiable) and by default will create this file with the permissions -rw-r--r--. Thus, if sensitive information is written to this file, other local users can read this information.\n\nFile.createTempFile(String, String) will create a temporary file in the system temporary directory if the 'java.io.tmpdir' system property is not explicitly set. \n\nThis affects the class\u00a0 https://github.com/apache/storm/blob/master/storm-core/src/jvm/org/apache/storm/utils/TopologySpoutLag.java#L99 \u00a0and was introduced by\u00a0 https://issues.apache.org/jira/browse/STORM-3123 \n\nIn practice, this has a very limited impact as this class is used only if\u00a0ui.disable.spout.lag.monitoring\n\n is set to false, but its value is true by default.\nMoreover, the temporary file gets deleted soon after its creation.\n\nThe solution is to use\u00a0 Files.createTempFile https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/nio/file/Files.html#createTempFile(java.lang.String,java.lang.String,java.nio.file.attribute.FileAttribute...) \u00a0instead.\n\nWe recommend that all users upgrade to the latest version of Apache Storm.\n\n"

      "value": "En sistemas tipo Unix, el directorio temporal se comparte entre todos los usuarios. Como tal, escribir en este directorio utilizando API que no establecen expl\u00edcitamente los permisos de archivo/directorio puede dar lugar a la divulgaci\u00f3n de informaci\u00f3n. Es de destacar que esto no afecta a los sistemas operativos MacOS modernos. El m\u00e9todo File.createTempFile en sistemas tipo Unix crea un archivo con un nombre predefinido (f\u00e1cilmente identificable) y, de forma predeterminada, crear\u00e1 este archivo con los permisos -rw-r--r--. Por lo tanto, si se escribe informaci\u00f3n confidencial en este archivo, otros usuarios locales pueden leer esta informaci\u00f3n. File.createTempFile(String, String) crear\u00e1 un archivo temporal en el directorio temporal del sistema si la propiedad del sistema 'java.io.tmpdir' no est\u00e1 configurada expl\u00edcitamente. Esto afecta a la clase https://github.com/apache/storm/blob/master/storm-core/src/jvm/org/apache/storm/utils/TopologySpoutLag.java#L99 y fue introducido por https://issues.apache.org/jira/browse/STORM-3123 En la pr\u00e1ctica, esto tiene un impacto muy limitado ya que esta clase se usa solo si ui.disable.spout.lag.monitoring est\u00e1 configurado en falso, pero su valor es verdadero de forma predeterminada. Adem\u00e1s, el archivo temporal se elimina poco despu\u00e9s de su creaci\u00f3n. La soluci\u00f3n es utilizar Files.createTempFile https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/nio/file/Files.html#createTempFile(java.lang.String,java.lang.String,java.nio.file.attribute.FileAttribute...) en su lugar. Recomendamos que todos los usuarios actualicen a la \u00faltima versi\u00f3n de Apache Storm."
