Detail
| 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. |

| Title: | DSA-2248-1 ejabberd -- denial of service | ||
| Description: | Wouter Coekaerts discovered that ejabberd, a distributed XMPP/Jabber server written in Erlang, is vulnerable to the so-called "billion laughs" attack because it does not prevent entity expansion on received data. This allows an attacker to perform denial of service attacks against the service by sending specially crafted XML data to it. | ||
