How to fix?

Upgrade Chainguard conductor to version 3.31.0-r4 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream conductor package and not the conductor package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

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.
