How to fix?

Upgrade Centos:6 libxml2-python to version 0:2.7.6-20.el6_7.1 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 xmlParseXMLDecl function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to obtain sensitive information via an (1) unterminated encoding value or (2) incomplete XML declaration in XML data, which triggers an out-of-bounds heap read.
