On Unix like systems, the system's temporary directory is shared between all users on that system. Because of this, when files and directories are written into this directory they are, by default, readable by other users on that same system. This vulnerability does not allow other users to overwrite the contents of these directories or files. This is purely an information disclosure vulnerability. This vulnerability impacts you if the JUnit tests write sensitive information, like API keys or passwords, into the temporary folder, and the JUnit tests execute in an environment where the OS has other untrusted users. Because certain JDK file system APIs were only added in JDK 1.7, this this fix is dependent upon the version of the JDK you are using. For Java 1.7 and higher users: this vulnerability is fixed in 4.13.1. For Java 1.6 and lower users: no patch is available, you must use the workaround below. If you are unable to patch, or are stuck running on Java 1.6, specifying the `java.io.tmpdir` system environment variable to a directory that is exclusively owned by the executing user will fix this vulnerability. For more information, including an example of vulnerable code, see the referenced GitHub Security Advisory."}, {"lang": "es", "value": "En JUnit4 desde la versi\u00f3n y antes de la versi\u00f3n 4.13.1, la regla de prueba TemporaryFolder contiene una vulnerabilidad de divulgaci\u00f3n de informaci\u00f3n local. En sistemas similares a Unix, el directorio temporal del sistema es compartido entre todos los usuarios de ese sistema. Debido a esto, cuando los archivos y directorios se escrib\u00edan en este directorio, son, por defecto, legibles por otros usuarios en ese mismo sistema. Esta vulnerabilidad no permite que otros usuarios sobrescriban el contenido de estos directorios o archivos. Esto es solamente una vulnerabilidad de divulgaci\u00f3n de informaci\u00f3n. Esta vulnerabilidad lo impacta si las pruebas de JUnit escriben informaci\u00f3n confidencial, como claves de API o contrase\u00f1as, en la carpeta temporal, y las pruebas de JUnit son ejecutados en un entorno donde el sistema operativo posee otros usuarios que no son de confianza. Debido a que determinadas API del sistema de archivos JDK solo fueron agregadas en JDK versi\u00f3n 1.7. Esta correcci\u00f3n depende de la versi\u00f3n del JDK que est\u00e9 usando. Para usuarios de Java versi\u00f3n 1.7 y posteriores: esta vulnerabilidad se corrigi\u00f3 en la versi\u00f3n 4.13.1. Para usuarios de Java versi\u00f3n 1.6 y anteriores: ning\u00fan parche est\u00e1 disponible, debe utilizar la siguiente soluci\u00f3n. Si no es capaz de parchear, o est\u00e1 bloqueado al ejecutar Java versi\u00f3n 1.6, especificar la variable de entorno del sistema \"java.io.tmpdir\" en un directorio que es propiedad exclusiva del usuario que lo ejecuta, solucionar\u00e1 esta vulnerabilidad.
