Descriptions

The Ubuntu SELinux initscript before version 1:0.10 used touch to create a lockfile in a world-writable directory. If the OS kernel does not have symlink protections then an attacker can cause a zero byte file to be allocated on any writable filesystem.

El initscript de Ubuntu SELinux anterior a la versión 1:0.10 utiliza el tacto para crear un LockFile en un directorio de escritura mundial. Si OS kernel no tiene protecciones symlink, entonces un atacante puede provocar que un archivo de cero bytes se asigne en cualquier sistema de archivos de escritura.
