Synopsis

========

 

A design error in Openfire might lead to a Denial of Service.

 

Background

==========

 

Openfire (formerly Wildfire) is a Java implementation of a complete

Jabber server.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 net-im/openfire < 3.5.0 >= 3.5.0

 

Description

===========

 

Openfire's connection manager in the file ConnectionManagerImpl.java

cannot handle clients that fail to read messages, and has no limit on

their session's send buffer.

 

Impact

======

 

Remote authenticated attackers could trigger large outgoing queues

without reading messages, causing a Denial of Service.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All Openfire users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=net-im/openfire-3.5.0"
