GHSA-g693-v3jr-8hcr: Duplicate Advisory: `ed25519-dalek` Double Public Key Signing Function Oracle Attack
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-w5vr-6qhr-36cc. This link is maintained to preserve external references.
Original Description
The ed25519-dalek crate before 2 for Rust allows a double public key signing function oracle attack. The Keypair implementation leads to a simple computation for extracting a private key.
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.
