(RHSA-2011:0882) Low: Red Hat Network Satellite server jabberd security update

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

It was found that the jabberd daemon did not properly detect recursion
during entity expansion. A remote attacker could provide a
specially-crafted XML file containing a large number of nested entity
references, which once processed by the jabberd daemon, could lead to a
denial of service (excessive memory and CPU consumption). (CVE-2011-1755)

Red Hat would like to thank Nico Golde of the Debian Security Team for
reporting this issue. The Debian Security Team acknowledges Wouter
Coekaerts as the original reporter.

Users of Red Hat Network Satellite 5.4.1 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.
