NVD Description
Note: Versions mentioned in the description apply only to the upstream bubblewrap.src package and not the bubblewrap.src package as distributed by RHEL.
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.
