An update for subscription-manager, subscription-manager-migration-data, and python-rhsm is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) 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.
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) :
Red Hat would like to thank Robert Scheck for reporting this issue.

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.
