Severity

Unknown

Summary

Ed25519 Signature Malleability in ed25519-java Due to Missing Scalar Range Check

Description

The implementation of EdDSA in EdDSA-Java (aka ed25519-java) through 0.3.0 exhibits signature malleability and does not satisfy the SUF-CMA (Strong Existential Unforgeability under Chosen Message Attacks) property. This allows attackers to create new valid signatures different from previous signatures for a known message.
