Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Red Hat/openshell, Red Hat/openshift/ose-rhel-coreos-8, Red Hat/openshift/ose-rhel-coreos-9.
  2. 2Review the reported fix. Source-reported workaround: Set GSSAPIDelegateCredentials to no where that option exists, or set GSSAPIAuthentication to no if GSSAPI authentication is not required.

  • Source referencebugzilla.redhat.com
Upstream source description

A flaw was found in OpenSSH. With GSSAPI authentication enabled, a failed GSSAPI attempt can leave delegated credentials stored for the connection even though user authorization did not succeed. A later successful login on that connection is not authorized by the leftover state.
