Topic

Updated rhn-client-tools packages that fix one security issue are now
available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate
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.

Description

Red Hat Network Client Tools provide programs and libraries that allow your
system to receive software updates from the Red Hat Network (RHN).

It was discovered that rhn-client-tools set insecure permissions on the
loginAuth.pkl file, used to store session credentials for authenticating
connections to Red Hat Network servers. A local, unprivileged user could
use these credentials to download packages from the Red Hat Network. They
could also manipulate package or action lists associated with the system's
profile. (CVE-2010-1439)

Users of rhn-client-tools are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue.

Solution

Before applying this update, make sure all previously-released errata
