Descriptions

bubblewrap.c in Bubblewrap before 0.3.3 misuses temporary directories in /tmp as a mount point. In some particular configurations (related to XDG_RUNTIME_DIR), a local attacker may abuse this flaw to prevent other users from executing bubblewrap or potentially execute code.

El archivo bubblewrap.c en Bubblewrap anterior de versión 0.3.3, utiliza de manera incorrecta directorios temporales en /tmp como un punto de montaje. En algunas configuraciones particulares (relacionadas con XDG_RUNTIME_DIR), un atacante local puede abusar de este defecto para prevenir que otros usuarios ejecuten bubblewrap o potencialmente ejecute código.
