Summary
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" message causing Filecoin nodes consuming F3 messages to become vulnerable. A "poison" message 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.
Risk Assessment
An attacker could cause Filecoin nodes to crash, leading to disruption of network or services relying on F3, and could be used for DoS attacks.
Recommendation
It is recommended to update go-f3 to version 0.8.7 or later, which includes a fix for the integer overflow issue.
