Descriptions
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_limit: reject configurations that cause integer overflow
Reject bogus configs where internal token counter wraps around.
This only occurs with very very large requests, such as 17gbyte/s.
Its better to reject this rather than having incorrect ratelimit.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: netfilter: nft_limit: rechazar configuraciones que causan desbordamiento de enteros Rechazar configuraciones falsas donde el contador de token interno se ajusta. Esto sólo ocurre con solicitudes muy grandes, como 17 gbytes/s. Es mejor rechazar esto en lugar de tener un límite de tasa incorrecto.
