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.

The subscription-manager-migration-data package provides certificates for
migrating a system from the legacy Red Hat Network Classic (RHN) to Red Hat
Subscription Management (RHSM).

The python-rhsm packages provide a library for communicating with the
representational state transfer (REST) interface of a Red Hat Unified
Entitlement Platform. The Subscription Management tools use this interface
to manage system entitlements, certificates, and access to content.

The following packages have been upgraded to a newer upstream version:
subscription-manager (1.17.15), python-rhsm (1.17.9),
subscription-manager-migration-data (2.0.31). (BZ#1328553, BZ#1328555,
BZ#1328559)

Security Fix(es):

* It was found that subscription-manager set weak permissions on files in
/var/lib/rhsm/, causing an information disclosure. A local, unprivileged
user could use this flaw to access sensitive data that could potentially be
used in a social engineering attack. (CVE-2016-4455)

Red Hat would like to thank Robert Scheck for reporting this issue.

Additional Changes:

Enterprise Linux 7.3 Release Notes linked from the References section.
