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"
