Doc Type: If docs needed, set a value
Doc Text:
A credentials leak was found in the OpenShift Container Platform. The private key for the external cluster certificate was stored incorrectly in the oauth-serving-cert ConfigMaps, and accessible to any authenticated OpenShift user or service-account. This flaw allows a malicious user to read the oauth-serving-cert ConfigMap in the openshift-config-managed namespace, compromising any web traffic secured using that certificate.

Hi everyone,

is there any existing plan to back-port the fix to OpenShift v4.9 as well?


Thanks in advance,
Marcus

Hi Marcus,


The fix for 4.9 is tracked in BZ 2107027.
Comment 12 Marcus 2022-08-02 05:32:46 UTC 
THX @oarribas, unfortunately I'm not allowed to access. Is there a reason why for v4.9 it's a private RH BZ?... and for v4.10 it's public
