How to fix?

Upgrade Centos:6 libxml2 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 package and not the libxml2 package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

The htmlParseComment function in HTMLparser.c in libxml2 allows attackers to obtain sensitive information, cause a denial of service (out-of-bounds heap memory access and application crash), or possibly have unspecified other impact via an unclosed HTML comment.
