This update fixes the following bug among others:

  • Previously, resources for the ClusterOperator were being created early in the update process, which led to update failures when the ClusterOperator had no status condition while Operators were updating. This bug fix changes the timing of when these resources are created. As a result, updates can take place without errors. (BZ#1959238)

Security Fix(es):

  • gogo/protobuf: plugin/unmarshal/unmarshal.go lacks certain index validation (CVE-2021-3121)
