| Doc Text: |
A flaw was discovered in FasterXML jackson-databind, where it would permit polymorphic deserialization of malicious objects using the ehcache gadget when used in conjunction with polymorphic type handling methods such as `enableDefaultTyping()` or when @JsonTypeInfo is using `Id.CLASS` or `Id.MINIMAL_CLASS` or in any other way which ObjectMapper.readValue might instantiate objects from unsafe sources. An attacker could use this flaw to execute arbitrary code.

fedora seems to be not affected by this, as we have jackson-databind 2.10.1 in fedora 30, 31, and rawhide: https://apps.fedoraproject.org/packages/jackson-databind 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 Mobile Application Platform is now End of Life: https://access.redhat.com/support/policy/updates/rhmap 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 JBoss AMQ Via RHSA-2020:0939 https://access.redhat.com/errata/RHSA-2020:0939 This bug is now closed. Further updates for individual products will be reflected on the CVE page(s): https://access.redhat.com/security/cve/cve-2019-20330 This issue has been addressed in the following products: Red Hat Single Sign-On Via RHSA-2020:0951 https://access.redhat.com/errata/RHSA-2020:0951 Upstream fix: https://github.com/FasterXML/jackson-databind/commit/fc4214a883dc087070f25da738ef0d49c2f3387e This issue has been addressed in the following products: Red Hat Openshift Application Runtimes Via RHSA-2020:2067 https://access.redhat.com/errata/RHSA-2020:2067 This issue has been addressed in the following products: EAP-CD 19 Tech Preview Via RHSA-2020:2333 https://access.redhat.com/errata/RHSA-2020:2333 This issue has been addressed in the following products: Red Hat Fuse 7.7.0 Via RHSA-2020:3192 https://access.redhat.com/errata/RHSA-2020:3192 This issue has been addressed in the following products: Red Hat Decision Manager Via RHSA-2020:3196 https://access.redhat.com/errata/RHSA-2020:3196 This issue has been addressed in the following products: Red Hat Process Automation Via RHSA-2020:3197 https://access.redhat.com/errata/RHSA-2020:3197 |
