Summary: An updated jabberd package that fixes one security issue is now available for Red Hat Network Satellite 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. 2. Relevant releases/architectures: Red Hat Network Satellite Server 5.5 (RHEL v.5) - s390x, x86_64 Red Hat Network Satellite Server 5.5 (RHEL v.6) - s390x, x86_64 3. Description: 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. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 Run the following command to restart the Red Hat Network Satellite server: # rhn-satellite restart 5.
