RHSA-2017:0698 - Security Advisory

Topic

An update for subscription-manager, subscription-manager-migration-data, and python-rhsm is now available for Red Hat Enterprise Linux 6.

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.

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 later upstream version: subscription-manager (1.18.10), python-rhsm (1.18.6), subscription-manager-migration-data (2.0.34). (BZ#1383475, BZ#1385446, BZ#1385382)

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.
