CVE-2016-1833 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:17.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libxml2 package and not the libxml2 package as distributed by Ubuntu.
The htmlCurrentChar function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted XML document.
