Debian DSA-2249-1 : jabberd14 - denial of service

medium Nessus Plugin ID 55037

Synopsis

The remote Debian host is missing a security-related update.

Description

Wouter Coekaerts discovered that jabberd14, an instant messaging server using the Jabber/XMPP protocol, 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.

The oldstable distribution (lenny), does not contain jabberd14.

Solution

Upgrade the jabberd14 packages.

For the stable distribution (squeeze), this problem has been fixed in version 1.6.1.1-5+squeeze1.
