CVE-2016-4447  (opens in a new tab)
CWE-122  (opens in a new tab)

How to fix?

Upgrade Centos:7 libxml2-devel to version 0:2.9.1-6.el7_2.3 or higher.

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.

The xmlParseElementDecl function in parser.c in libxml2 before 2.9.4 allows context-dependent attackers to cause a denial of service (heap-based buffer underread and application crash) via a crafted file, involving xmlParseName.
