GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

CVE-2020-36843 (GCVE-0-2020-36843)

Vulnerability from cvelistv5 – Published: 2025-03-13 00:00 – Updated: 2025-03-18 16:22
VLAI
Summary
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.
Severity
