CVE-2025-59942

go-f3 is a Golang implementation of Fast Finality for Filecoin (F3). In versions 0.8.6 and below, go-f3 panics when it validates a "poison" messages causing Filecoin nodes consuming F3 messages to become vulnerable. A "poison" message can can cause integer overflow in the signer index validation, which can cause the whole node to crash. These malicious messages aren't self-propagating since the bug is in the validator. An attacker needs to directly send the message to all targets. This issue is fixed in version 0.8.7.

Summary		(es) go-f3 es una implementación en Golang de Fast Finality para Filecoin (F3). En las versiones 0.8.6 e inferiores, go-f3 entra en pánico cuando valida mensajes 'envenenados', lo que hace que los nodos de Filecoin que consumen mensajes F3 se vuelvan vulnerables. Un mensaje 'envenenado' puede causar un desbordamiento de entero en la validación del índice del firmante, lo que puede provocar la caída de todo el nodo. Estos mensajes maliciosos no se autopropagan, ya que el error está en el validador. Un atacante necesita enviar directamente el mensaje a todos los objetivos. Este problema está solucionado en la versión 0.8.7.
