Security Fix(es):

  * An out-of-bounds read flaw was found in the way Expat processed certain
input. A remote attacker could send specially crafted XML that, when parsed
by an application using the Expat library, would cause that application to
crash or, possibly, execute arbitrary code with the permission of the user
running the application. (CVE-2016-0718)

Red Hat would like to thank Gustavo Grieco for reporting this issue.");
