Denial Of Service (DoS)

@chainsafe/lodestar is vulnerable to denial of service. The vulnerability exists because the library uses the uint64 values as native javascript numbers, allowing an attacker to crash the application by providing large uint64 values greater than 2^53 through the maliciously-crafted AttesterSlashi...

AttesterSlashing number overflow

Impact Possible consensus split given maliciously-crafted AttesterSlashing or ProposerSlashing being included on-chain. Since we represent uint64 values as native javascript numbers, there is an issue when those variables with large greater than 2^53 uint64 values are included on chain. In those...

CVE-2022-29219

Lodestar is a TypeScript implementation of the Ethereum Consensus specification. Prior to version 0.36.0, there is a possible consensus split given maliciously-crafted AttesterSlashing or ProposerSlashing being included on-chain. Because the developers represent uint64 values as native javascript...

CVE-2022-29219

Lodestar (TypeScript Ethereum Consensus) before v0.36.0 is vulnerable due to using native JavaScript numbers for uint64 values in AttesterSlashing/ProposerSlashing, causing rounding errors for large values (>2^53). This can yield consensus splits or valid Slashing being treated as invalid, pot...
