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...

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...

Frontier 安全漏洞

Frontier is an EtherCompatible layer for Substrate. It is used to run unmodified Ethernet Dapps. Frontier suffers from a security vulnerability that stems from the truncation done during the conversion between EVM Balance Type and Substrate Balance Type being incorrectly implemented, resulting in...

CVE-2022-31111: Always-Incorrect Control Flow Implementation

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...

Frontier numeric error vulnerability

Frontier is an ethereum-compatible layer of Substrate. A numeric error vulnerability exists in Frontier, which stems from a bug in Frontier's pre-compiled implementation of MODEXP that could lead to integer underflow in some cases. This would cause the node of the debug build to crash. No detaile...

Integer underflow in Frontier

Impact A bug in Frontier's MODEXP precompile implementation can cause an integer underflow in certain conditions. This will cause a node crash for debug builds. For release builds and production WebAssembly binaries, the impact is limited as it can only cause a normal EVM out-of-gas. It is...
