CVE-2014-3660  (opens in a new tab)
CWE-400  (opens in a new tab)

How to fix?

Upgrade Centos:7 libxml2 to version 0:2.9.1-5.el7_0.1 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:7 relevant fixed versions and status.

parser.c in libxml2 before 2.9.2 does not properly prevent entity expansion even when entity substitution has been disabled, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted XML document containing a large number of nested entity references, a variant of the "billion laughs" attack.
