JSON

modules/xmpp/serv_xmpp.c in Citadel 7.86 and earlier 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.
