CVE-2023-45130 Frontier opcode SUICIDE touches too many storage values on large contracts

Frontier is Substrate's Ethereum compatibility layer. Prior to commit aea528198b3b226e0d20cce878551fd4c0e3d5d0, at the end of a contract execution, when opcode SUICIDE marks a contract to be deleted, the software uses storage::removeprefix now renamed to storage::clearprefix to remove all storage...

CVE-2023-28431

Frontier is an Ethereum compatibility layer for Substrate. Frontier's modexp precompile uses num-bigint crate under the hood. In the implementation prior to pull request 1017, the cases for modulus being even and modulus being odd are treated separately. Odd modulus uses the fast Montgomery...

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 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.

CVE-2022-36008

Frontier is Substrate's Ethereum compatibility layer. A security issue was discovered affecting parsing of the RPC result of the exit reason in case of EVM reversion. In release build, this would cause the exit reason being incorrectly parsed and returned by RPC. In debug build, this would cause ...

CVE-2022-36008 Message length overflow in frontier

Frontier is Substrate's Ethereum compatibility layer. A security issue was discovered affecting parsing of the RPC result of the exit reason in case of EVM reversion. In release build, this would cause the exit reason being incorrectly parsed and returned by RPC. In debug build, this would cause ...

CVE-2022-31111 Discrepency in transfer value and actual value due to incorrect truncation in Frontier

Frontier is Substrate's Ethereum compatibility layer. In affected versions the truncation done when converting between EVM balance type and Substrate balance type was incorrectly implemented. This leads to possible discrepancy between appeared EVM transfer value and actual Substrate value...

CVE-2022-31111

Frontier (Substrate’s Ethereum compatibility layer) is affected by a truncation error when converting between EVM balance type and Substrate balance type. In affected versions this can cause a discrepancy between the appeared EVM transfer value and the actual Substrate value transferred. The issu...

GHSA-X5F3-QMWJ-4F84 Authentication bypass by capture-replay in github.com/cosmos/ethermint

Cosmos Network Ethermint = v0.4.0 is affected by a cross-chain transaction replay vulnerability in the EVM module. Since ethermint uses the same chainIDEpoch and signature schemes with ethereum for compatibility, a verified signature in ethereum is still valid in ethermint with the same msg conte...

Input validation

Frontier is Substrate's Ethereum compatibility layer. In the newly introduced signed Frontier-specific extrinsic for pallet-ethereum, a large part of transaction validation logic was only called in transaction pool validation, but not in block execution. Malicious validators can take advantage of...

CVE-2021-41138 Validity check for signed Frontier-specific extrinsic not called in block execution

Frontier is Substrate's Ethereum compatibility layer. In the newly introduced signed Frontier-specific extrinsic for pallet-ethereum, a large part of transaction validation logic was only called in transaction pool validation, but not in block execution. Malicious validators can take advantage of...
