GHSA-FCMM-54JP-7VF6 Frontier's modexp precompile is slow for even modulus

Impact Frontier's modexp precompile uses num-bigint crate under the hood. In the implementation, the cases for modulus being even and modulus being odd are treated separately. Odd modulus uses the fast Montgomery multiplication, and even modulus uses the slow plain power algorithm. This gas cost...

CVE-2022-39242

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...

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...
