Severity: Normal
Title: Openfire: Denial of Service
Date: April 23, 2008
Bugs: #217234
ID: 200804-26

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"
