Comment 4 Chess Hazlett 2020-06-19 16:59:09 UTC 
Mitigation:

The following conditions are needed for an exploit, we recommend avoiding all if possible:
* Deserialization from sources you do not control
* enableDefaultTyping()
* @JsonTypeInfo using id.CLASS or id.MINIMAL_CLASS
* org.jsecurity.realm.jndi.JndiRealmFactory in classpath
Comment 15 Yadnyawalk Tale 2020-06-25 11:06:50 UTC 
Statement:

While OpenShift Container Platform's elasticsearch plugins do ship the vulnerable component, it doesn't do any of the unsafe things described in https://access.redhat.com/solutions/3279231. We may update the jackson-databind dependency in a future release.

Red Hat OpenStack Platform ships OpenDaylight, which contains the vulnerable jackson-databind. However, OpenDaylight does not expose jackson-databind in a way that would make it vulnerable, lowering the impact of the vulnerability for OpenDaylight. As such, Red Hat will not be providing a fix for OpenDaylight at this time.

The PKI module as shipped in Red Hat Enterprise Linux 8 and Red Hat Satellite 6 does not enable polymorphic deserialization which is a required configuration for the vulnerability to be used, lowering the impact of the vulnerability for the Product. We may update the jackson-databind dependency in a future release.

The version of jackson-databind as shipped in Red Hat Software Collections rh-maven35 is used only while building maven, thus it does not deserialize data coming from untrusted sources, lowering the impact of the vulnerability for the Product.
