Wei Lei discovered that libxml2 incorrecty handled certain parameter
entities. An attacker could use this issue with specially constructed XML
data to cause libxml2 to consume resources, leading to a denial of service
(CVE-2017-16932).

The libxml2 package has been updated to version 2.9.7 to fix these issues
and several other bugs.

Also, the perl-XML-LibXML package has been updated to version 2.13.200 to
allow it to be rebuilt against the updated libxml2.");
