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...

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...

Name of the Vulnerable Software and Affected Versions: Frontier versions prior to the deployment of pull request 1017 Description: The issue arises from the modexp precompile in Frontier, which uses the num-bigint crate. The implementation treats odd and even moduli differently, with odd moduli...

[Medium - 1] Ecrecover precompile doesn't behave the same as the one from Ethereum

Lines of code Vulnerability details Impact According to the Ethereum yellow paper and in the specifications of the ecrecover precompile, it is stated that if the ecrecover doesn't return anything denoted by ∅, then the return should be 0 as well. If we take a look at the current ecrecover...

Design/Logic Flaw

SputnikVM, also called evm, is a Rust implementation of Ethereum Virtual Machine. A custom stateful precompile can use the isstatic parameter to determine if the call is executed in a static context via STATICCALL, and thus decide if stateful operations should be done. Prior to version 0.36.0, th...
