"The remote Redhat Enterprise Linux 5 / 6 host has a package installed that is affected by a vulnerability as referenced
in the RHSA-2012:1538 advisory.

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

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
