How to fix?

Upgrade Debian:9 jackson-databind to version 2.8.6-1+deb9u7 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream jackson-databind package and not the jackson-databind package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

FasterXML jackson-databind 2.0.0 through 2.9.10.2 lacks certain xbean-reflect/JNDI blocking, as demonstrated by org.apache.xbean.propertyeditor.JndiConverter.
