How to fix?

There is no fixed version for Centos:7 libxml2-devel.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libxml2-devel package and not the libxml2-devel package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

There is a flaw in the xml entity encoding functionality of libxml2 in versions before 2.9.11. An attacker who is able to supply a crafted file to be processed by an application linked with the affected functionality of libxml2 could trigger an out-of-bounds read. The most likely impact of this flaw is to application availability, with some potential impact to confidentiality and integrity if an attacker is able to use memory information to further exploit the application.
