cri-tools may accept resumed TLS sessions after CA changes
published 18 days ago
Summary
The cri-tools software can mistakenly allow a secure connection to continue when the list of trusted certificate authorities is changed between the original and resumed handshake. This could let an unauthorized party keep a connection that should have been stopped. Update cri-tools to a version that fixes the handling of certificate authority changes.
What to do
- Update cleanstart cri-tools to version 1.29.0-r5.
