In affected versions a prepared statement using either `PreparedStatement.setText(int, InputStream)` or `PreparedStatemet.setBytea(int, InputStream)` will create a temporary file if the InputStream is larger than 2k. This will create a temporary file which is readable by other users on Unix like systems, but not MacOS. 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. 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. Java 1.7 and higher users: this vulnerability is fixed in 4.5.0. Java 1.6 and lower users: no patch is available. 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 mitigate this vulnerability."}, {"lang": "es", "value": "Es un componente postgresql JDBC de c\u00f3digo abierto. En las versiones afectadas, una declaraci\u00f3n preparada que utilice `PreparedStatement.setText(int, InputStream)` o `PreparedStatemet.setBytea(int, InputStream)` crear\u00e1 un archivo temporal si el InputStream es mayor que 2k. Esto crear\u00e1 un archivo temporal que otros usuarios podr\u00e1n leer en sistemas similares a Unix, pero no a MacOS. En sistemas tipo Unix, el directorio temporal del sistema se comparte entre todos los usuarios de ese sistema. Debido a esto, cuando los archivos y directorios se escriben en este directorio, de forma predeterminada, otros usuarios en ese mismo sistema pueden leerlos. Esta vulnerabilidad no permite que otros usuarios sobrescriban el contenido de estos directorios o archivos. Esto es puramente una vulnerabilidad de divulgaci\u00f3n de informaci\u00f3n. Debido a que ciertas API del sistema de archivos JDK solo se agregaron en JDK 1.7, esta soluci\u00f3n depende de la versi\u00f3n de JDK que est\u00e9 utilizando.
