CVE-2022-39242

CVE-2022-39242 affects Frontier, an Ethereum compatibility layer for Substrate. The root cause is that the worst-case weight was always counted as the block weight in all cases, allowing large EVM gas refunds to enable block spamming and inflate chain gas prices. The impact is limited: attack cos...

CVE-2022-39242 Incorrect Calculation in Frontier leads to inflated Ethereum chain gas prices

Frontier is an Ethereum compatibility layer for Substrate. Prior to commit d3beddc6911a559a3ecc9b3f08e153dbe37a8658, the worst case weight was always accounted as the block weight for all cases. In case of large EVM gas refunds, this can lead to block spamming attacks -- the adversary can constru...
