CVE-2016-9318 Open this link in a new tabHow to fix?
Upgrade Alpine:3.9 libxml2 to version 2.9.4-r2 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 Alpine.
See How to fix? for Alpine:3.9 relevant fixed versions and status.
libxml2 2.9.4 and earlier, as used in XMLSec 1.2.23 and earlier and other products, does not offer a flag directly indicating that the current document may be read but other files may not be opened, which makes it easier for remote attackers to conduct XML External Entity (XXE) attacks via a crafted document.
