How to Fix CVE-2022-36008

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

fc-rpc fixed: Latest secure release 
Upgrade fc-rpc to Latest secure release
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 fc-rpc

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-36008, inspect your project dependencies for Fc rpc:

inspect dependencies for fc-rpc

Analyze the terminal output to locate any version of Fc rpc in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), 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-190: Integer Overflow or Wraparound, where the product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. this occurs when an integer value is incremented to a value that is too large to store in the associated representation. when this occurs, the value may become a very small or negative number. In Fc rpc, 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 low severity security issue was discovered affecting parsing of the RPC result of the exit reason in case of EVM reversion. In release build, this would cause the exit reason being incorrectly parsed and returned by RPC. In debug build, this would cause an overflow panic. No action is needed unless you have a bridge node that needs to distinguish different reversion exit reasons and you used RPC for this. ### Patches The issue is patched in https://github.com/paritytech/frontier/pull/820 ### Workarounds None. ### References PR https://github.com/paritytech/frontier/pull/820 ### For more information If you have any questions or comments about this advisory: * Email [Wei Tang](mailto:wei@that.world)
