This fix was incomplete: on 64-bit platforms, the seccomp filter could be bypassed by an ioctl request number that has TIOCSTI in its 32 least significant bits and an arbitrary nonzero value in its 32 most significant bits, which the Linux kernel would treat as equivalent to TIOCSTI."}, {"lang": "es", "value": "Flatpak, en versiones anteriores a la 1.0.8, 1.1.x y 1.2.x anteriores a la 1.2.4, y en las versiones 1.3.x anteriores a la 1.3.1, permite omitir el sandbox.
