Topic

available for Red Hat Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having moderate

which gives a detailed severity rating, is available from the CVE link in
the References section.
Description
The subscription-manager packages provide programs and libraries to allow
users to manage subscriptions and yum repositories from the Red Hat
Entitlement platform.
It was discovered that the rhn-migrate-classic-to-rhsm tool did not verify
the Red Hat Network Classic server's X.509 certificate when migrating
system profiles registered with Red Hat Network Classic to
Certificate-based Red Hat Network. An attacker could use this flaw to
conduct man-in-the-middle attacks, allowing them to obtain the user's Red
Hat Network credentials. (CVE-2012-6137)
This issue was discovered by Florian Weimer of the Red Hat Product Security
Team.
All users of subscription-manager are advised to upgrade to these updated
packages, which contain a backported patch to fix this issue.
