RHEL 6 : subscription-manager (RHSA-2017:0698)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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.

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.
