Insufficient Control Flow Management

Evmos is vulnerable to Insufficient Control Flow Management. The vulnerability is due to different ante handler checks for Cosmos and Ethereum transactions, allowing a clawback account to bypass Cosmos checks by sending an Ethereum transaction targeting a precompile used to interact with a Cosmos...

CVE-2024-37158

Evmos is the Ethereum Virtual Machine EVM Hub on the Cosmos Network. Preliminary checks on actions computed by the clawback vesting accounts are performed in the ante handler. Evmos core, implements two different ante handlers: one for Cosmos transactions and one for Ethereum transactions. Checks...

CVE-2023-37902

Vyper is a Pythonic programming language that targets the Ethereum Virtual Machine EVM. Prior to version 0.3.10, the ecrecover precompile does not fill the output buffer if the signature does not verify. However, the ecrecover builtin will still return whatever is at memory location 0. This means...

CVE-2023-28431

CVE-2023-28431 describes a vulnerability in Frontier’s modexp precompile used by Substrate. The implementation treats even and odd moduli differently: odd moduli use Montgomery multiplication, while even moduli fall back to a slower plain power algorithm. This mismatch caused a gas-cost discrepan...

CVE-2023-28431 Frontier's modexp precompile is slow for even modulus

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...
