Synopsis

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

2.  Impact Information

Background

Openfire (formerly Wildfire) is a Java implementation of a complete Jabber server.

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.

3.  Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All Openfire users should upgrade to the latest version:

Code Listing 3.1: Resolution

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