Created jackson-databind tracking bugs for this issue: Affects: fedora-all [bug 1821312]
Upstream fix: https://github.com/FasterXML/jackson-databind/commit/05d7e0e13f43e12db6a51726df12c8b4d8040676
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`
This issue has been addressed in the following products: Red Hat Software Collections for Red Hat Enterprise Linux 7 Red Hat Software Collections for Red Hat Enterprise Linux 7.5 EUS Red Hat Software Collections for Red Hat Enterprise Linux 7.6 EUS Red Hat Software Collections for Red Hat Enterprise Linux 7.7 EUS Via RHSA-2020:1523 https://access.redhat.com/errata/RHSA-2020:1523
Statement: Red Hat Satellite 6 does not enable polymorphic deserialization which is a required configuration for the vulnerability to be used. 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. 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. The PKI module as shipped in Red Hat Enterprise Linux 8 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.
