sodiumoxide fixed: 0.2.5 
Upgrade sodiumoxide to 0.2.5
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 sodiumoxide

How to Check if You Are Affected

To determine whether your application is affected by CVE-2019-25002, inspect your project dependencies for Sodiumoxide:

inspect dependencies for sodiumoxide

Analyze the terminal output to locate any version of Sodiumoxide in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.2.5), 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-697: Incorrect Comparison, where the product compares two entities in a security-relevant context, but the comparison is incorrect. In Sodiumoxide, 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

An issue was discovered in the sodiumoxide crate starting with 0.2.0 and prior to 0.2.5 for Rust. `generichash::Digest::eq` compares itself to itself and thus has degenerate security properties.
