CVE-2011-2205
First published: Wed Jun 22 2011(Updated: )
Prosody before 0.8.1 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.
