How to Fix CVE-2022-39354

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: 0.36.0 
Upgrade evm to 0.36.0
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-2022-39354, 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 0.36.0), 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-670: Always-Incorrect Control Flow Implementation, where the code contains a control flow path that does not reflect the algorithm that the path is intended to implement, leading to incorrect behavior any time this path is navigated. 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 A custom stateful precompile can use the `is_static` parameter to determine if the call is executed in a static context (via `STATICCALL`), and thus decide if stateful operations should be done. Previously, the passed `is_static` parameter was incorrect -- it was only set to `true` if the call comes from a **direct** `STATICCALL` opcode. However, once a static call context is entered, it should stay static. The issue only impacts custom precompiles that actually uses `is_static`. The maintainers estimate the usage is low. However, for those affected, it can lead to possible incorrect state transitions. ### Patches PR: https://github.com/rust-blockchain/evm/pull/133 Released in v0.36.0. Older patch versions can be released on request if anyone needs them. Simply contact @sorpaas by email to request it. ### For more information If you have any questions or comments about this advisory: * Open an issue in [evm repo](https://github.com/rust-blockchain/evm) * Email Wei at [wei@that.world](mailto:wei@that.world)
