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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):

885130 - CVE-2012-6137 subscription-manager: rhn-migrate-classic-to-rhsm missing SSL certificate verification
