Created jackson-databind tracking bugs for this issue:

Affects: fedora-all [bug 1752964]

Comment 5 Cedric Buissart 🐶 2019-09-23 10:11:45 UTC

OpenDaylight provided as part of Red Hat OpenStack does not utilize logback when used in a supported configuration. Therefore, the prerequisites for this vulnerability are not present and OpenDaylight is not affected.

Satellite 6 does not enable polymorphic unmarshmalling, which is a required configuration for the vulnerability to be used. We may update the jackson-databind dependency in a future release.
