expat_erl.c in ejabberd before 2.1.7 and 3.x before 3.0.0-alpha-3, and
exmpp before 0.9.7, does not properly detect recursion during entity
expansion, which allows remote attackers to cause a denial of service
(memory and CPU consumption) via a crafted XML document containing a large
number of nested entity references, a similar issue to CVE-2003-1564.
