CVE-2022-31111

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-2025-49812 Apache HTTP Server: mod_ssl TLS upgrade attack

In some modssl configurations on Apache HTTP Server versions through to 2.4.63, an HTTP desynchronisation attack allows a man-in-the-middle attacker to hijack an HTTP session via a TLS upgrade. Only configurations using "SSLEngine optional" to enable TLS upgrades are affected. Users are recommend...

Design/Logic Flaw

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-2023-45130

Frontier (Substrate’s Ethereum compatibility layer) has a CVE-2023-45130 issue where, prior to commit aea528198b3b226e0d20cce878551fd4c0e3d5d0, invoking opcode SUICIDE on a contract that has large storage can trigger a single IO call across the WebAssembly boundary to remove all storages, potenti...

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-2022-31111

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...
