(RHSA-2013:0788) Moderate: subscription-manager security update

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.
