How to Fix CVE-2024-58265

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

snow fixed: 0.9.5 
Upgrade snow to 0.9.5
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 snow

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-58265, inspect your project dependencies for Snow:

inspect dependencies for snow

Analyze the terminal output to locate any version of Snow in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.9.5), 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-440: Expected Behavior Violation, where a feature, api, or function does not perform according to its specification. In Snow, 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 There was a logic bug where unauthenticated payloads could still cause a nonce increment in snow's internal state. For an attacker with the ability to inject packets into the channel Noise is talking over, this allows a denial-of-service type attack which could prevent communication as it causes the sending and receiving side to be expecting different nonce values than would arrive. Note that this only affects those who are using the stateful `TransportState`, not those using `StatelessTransportState`. ### Patches This has been patched in version 0.9.5, and all users are recommended to update. ### References There will be a more formal report of this in the near future.
