How to fix?

Upgrade Centos:6 libxml2-python to version 0:2.7.6-21.el6_8.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libxml2-python package and not the libxml2-python package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

The xmlStringGetNodeList function in tree.c in libxml2 2.9.3 and earlier, when used in recovery mode, allows context-dependent attackers to cause a denial of service (infinite recursion, stack consumption, and application crash) via a crafted XML document.
