A \"poison\" message can can cause integer overflow in the signer index validation.  In Lotus' case, the whole node will crash.  \n\nThere is no barrier to entry.  An attacker doesn't need any power to pull off this attack.\n\nThese malicious messages aren't self-propagating since the bug is in the validator.  An attacker needs to directly send the message to all targets.\n\n\n\n### Patches\nThe fix was merged and released with go-f3 0.8.7.  All node software (Lotus, Forest, Venus) are using a patched version of go-f3 with their updates for the nv27 network upgrade.\n\ngo-f3 now does proper overflow checking using `math.MaxInt64` comparison and returns error `\"justificationPower overflow\"` when overflow would occur.\n\n### Workarounds\nThe are no immediate workarounds available.  Nodes should upgrade to the patched version, which they will have done if participating in nv27 on Filecoin mainnet.\n\n### Credits\nThe initial finding(unrelated path) was reported by [0xNirix](https://github.com/0xNirix) via bug bounty program which wasn't high issue. The further digging by developers led to this finding.
