are now available for Red Hat Network Satellite 5.4.1 for Red Hat

which give detailed severity ratings, are available for each vulnerability

Description

Red Hat Network (RHN) Satellite provides a solution to organizations
requiring absolute control over and privacy of the maintenance and package
deployment of their servers. It allows organizations to utilize the
benefits of the Red Hat Network without having to provide public Internet
access to their servers or other client systems.

Multiple cross-site scripting (XSS) flaws were found in the RHN Satellite
web interface. A remote attacker could use these flaws to perform a
cross-site scripting attack against victims using the RHN Satellite web
interface. (CVE-2011-2919, CVE-2011-2920, CVE-2011-2927, CVE-2011-3344)

An open redirect flaw was found in the RHN Satellite web interface login
page. A remote attacker able to trick a victim to open the login page using
a specially-crafted link could redirect the victim to an arbitrary page
after they successfully log in. (CVE-2011-1594)

Red Hat would like to thank Daniel Karanja Muturi for reporting
CVE-2011-2919; Nils Juenemann and The Bearded Warriors for independently
reporting CVE-2011-2920; Nils Juenemann for reporting CVE-2011-2927;
Sylvain Maes for reporting CVE-2011-3344; and Thomas Biege of the SuSE
Security Team for reporting CVE-2011-1594.

This update also adds the following enhancement:

• Session cookies set by RHN Satellite are now marked as HTTPOnly. This

setting helps reduce the impact of cross-site scripting flaws by
instructing the browser to disallow scripts access to those cookies.
