Comment 1 Guilherme de Almeida Suckevicz 2020-03-31 13:40:53 UTC
Created jackson-databind tracking bugs for this issue:

Affects: fedora-all [bug 1819213]

Comment 2 Jonathan Christison 2020-03-31 15:57:10 UTC
This vulnerability is out of security support scope for the following products:

 * Red Hat JBoss Fuse 6
 * Red Hat JBoss A-MQ 6

Please refer to https://access.redhat.com/support/policy/updates/jboss_notes for more details.

Comment 15 Chess Hazlett 2020-04-09 00:14:01 UTC
Adjusting CVSS to NIST's: 7.5/CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N -> 8.8/CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H  per scoring discussion in task.

@rschiron not adjusting individual product impacts to moderate for rhel or rhscl, but JFYI so see the change and can verify if they should stay with the global impact or not.
@jochrist should amq-6 stay at OOSS for this as global impact moves to important?

Comment 19 Riccardo Schirone 2020-04-09 13:00:16 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`

Comment 23 Riccardo Schirone 2020-04-21 15:58:11 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.

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.

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.
