ntru fixed: Latest secure release 
Upgrade ntru 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 ntru

How to Check if You Are Affected

To determine whether your application is affected by GHSA-fq33-vmhv-48xh, inspect your project dependencies for ntru-rs has unsound FFI:

inspect dependencies for ntru

Analyze the terminal output to locate any version of ntru-rs has unsound FFI 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.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In ntru-rs has unsound FFI, 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

The following usage causes undefined behavior. ```rust let kp: ntru::types::KeyPair = …; kp.get_public().export(Default::default()) ``` When compiled with debug assertions, the code above will trigger a `attempt to subtract with overflow` panic before UB occurs. Other mistakes (e.g. using `EncParams` from a different key) may always trigger UB. Likely, older versions of this crate are also affected, but have not been tested.
