- 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.
