A design error in Openfire might lead to a Denial of Service.
|Package||net-im/openfire on all architectures|
|Affected versions||< 3.5.0|
|Unaffected versions||>= 3.5.0|
Openfire (formerly Wildfire) is a Java implementation of a complete Jabber server.
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.
Remote authenticated attackers could trigger large outgoing queues without reading messages, causing a Denial of Service.
There is no known workaround at this time.
All Openfire users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-im/openfire-3.5.0"
