Updated subscription-manager packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6.
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.
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.
