"An updated jabberd package that fixes one security issue is now
available for Red Hat Network Proxy 5.5 for Red Hat Enterprise Linux 5
and 6.

The Red Hat Security Response Team has rated this update as having low
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.

This package provides jabberd 2, an Extensible Messaging and Presence
Protocol (XMPP) server used for XML based communication.

It was discovered that the XMPP Dialback protocol implementation in
jabberd 2 did not properly validate Verify Response and Authorization
Response messages. A remote attacker able to connect to the jabberd's
server-to-server communication port could possibly use this flaw to
spoof source domains of the XMPP messages. (CVE-2012-3525)

Users of Red Hat Network Proxy 5.5 are advised to upgrade to this
updated jabberd package, which resolves this issue. For this update to
take effect, Red Hat Network Proxy must be restarted. Refer to the
Solution section for details."
