Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-323: Reusing a Nonce, Key Pair in Encryption, where nonces should be used for the present occasion and only once. In Duplicate Advisory, 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

### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-6878-6wc2-pf5h. This link is maintained to preserve external references. ### Original Description Versions of the package cocoon before 0.4.0 are vulnerable to Reusing a Nonce, Key Pair in Encryption when the encrypt, wrap, and dump functions are sequentially called. An attacker can generate the same ciphertext by creating a new encrypted message with the same cocoon object. **Note:** The issue does NOT affect objects created with Cocoon::new which utilizes ThreadRng.
