CVE-2011-1754

Estado: ModificadaMedia (5)—

jabberd14 1.6.1.1 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.
