Currently, Drill uses Jackson 2.7.1. The goal of this Jira is to update Jackson version to 2.7.8.
All Jackson versions 2.7.x before 2.7.8 have CVE-2016-7051 vulnerability.
The problem was with the jackson-dataformat-xml module (issue-211).
Drill does not use this module yet, but we want to update the version for the case when we start to use this module.
