Synopsis
=======
The jabberd server was found to be vulnerable to a remote Denial of
Service attack.
Background

Jabber is a set of streaming XML protocols enabling message, presence,
and other structured information exchange between two hosts. jabberd is
the original implementation of the Jabber protocol server.

Jose Antonio Calvo found a defect in routines handling XML parsing of
incoming data. jabberd 1.x may crash upon reception of invalid data on
any socket connection on which XML is parsed.
Impact

A remote attacker may send a specific sequence of bytes to an open
socket to crash the jabberd server, resulting in a Denial of Service.
Workaround
