Vulnerability from github – Published: 2022-01-14 21:03 – Updated: 2024-10-24 21:50

Summary

Integer underflow in Frontier

Details

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 recommended that you apply the patch as soon as possible.

If you do not use MODEXP precompile in your runtime, then you are not impacted.

Patches

Patches are applied in PR #549.

Workarounds

None.

CVE-2022-21685 (GCVE-0-2022-21685)

Vulnerability from cvelistv5 – Published: 2022-01-14 17:05 – Updated: 2025-04-23 19:11

Title

Integer underflow in Frontier

Summary

Frontier is Substrate's Ethereum compatibility layer. Prior to commit number `8a93fdc6c9f4eb1d2f2a11b7ff1d12d70bf5a664`, 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. Users who do not use MODEXP precompile in their runtime are not impacted. A patch is available in pull request #549.
