How to Fix GHSA-h864-m8vm-3xvj

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

oqs fixed: 0.7.2 
Upgrade oqs to 0.7.2
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 oqs

How to Check if You Are Affected

To determine whether your application is affected by GHSA-h864-m8vm-3xvj, inspect your project dependencies for Oqs:

inspect dependencies for oqs

Analyze the terminal output to locate any version of Oqs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.7.2), 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 General Security Weakness. In Oqs, 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

Ward Beullens found a practical key-recovery attack against Rainbow. The level I parametersets are removed from liboqs starting from version `0.7.2`. Find the scientific details in [Breaking Rainbow Takes a Weekend on a Laptop](https://eprint.iacr.org/2022/214). This means all the `oqs::sig::Algorithm::RainbowI*` variants are insecure.
