Loki package may accept revoked certificates

published 23 days ago
Summary

The Loki software can fail to recognize when a signing key has been revoked, allowing potentially untrusted code to be accepted as valid. This could let attackers introduce malicious components that appear legitimate. Update Loki to the latest version or apply the vendor’s patch to ensure revoked keys are correctly blocked.

What to do
  • Update cleanstart loki to version 3.7.1-r1.
