3. 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.
