How to Fix CVE-2024-21629

To remediate this vulnerability, upgrade all affected Evm dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

evm fixed: 0.41.1 
Upgrade evm to 0.41.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for evm

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-21629, inspect your project dependencies for Evm:

inspect dependencies for evm

Analyze the terminal output to locate any version of Evm in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.41.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-703: Improper Check or Handling of Exceptional Conditions, where the product does not properly anticipate or handle exceptional conditions that rarely occur during normal operation of the product. In Evm, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact In `rust-evm`, a feature called `record_external_operation` was introduced, allowing library users to record custom gas changes. This feature can have some bogus interactions with the call stack. In particular, during finalization of a `CREATE` or `CREATE2`, in the case that [the substack execution happens successfully](https://github.com/rust-ethereum/evm/blob/release-v041/src/executor/stack/executor.rs#L1012C25-L1012C69), `rust-evm` will first commit the substate, and then call `record_external_operation(Write(out_code.len()))`. If `record_external_operation` later fails, this error is returned to the parent call stack, instead of `Succeeded`. Yet, the substate commitment already happened. This causes smart contracts able to commit state changes, when the parent caller contract receives zero address (which usually indicates that the execution has failed). This issue only impacts library users with custom `record_external_operation` that returns errors. ### Patches The issue is patched in release 0.41.1. The commit can be seem [here](https://github.com/rust-ethereum/evm/commit/d8991ec727ad0fb64fe9957a3cd307387a6701e4). ### Workarounds None. ### References Patch PR [#264](https://github.com/rust-ethereum/evm/pull/264).
