GHSA-97f8-h76h-f297: Duplicate Advisory: Unauthenticated Nonce Increment in snow
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-7g9j-g5jg-3vv3. This link is maintained to preserve external references.
Original Description
The snow crate before 0.9.5 for Rust, when stateful TransportState is used, allows incrementing a nonce and thereby denying message delivery.
Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
