Test ID:1.3.6.1.4.1.25623.1.0.871785
Category:Red Hat Local Security Checks
Title:RedHat Update for subscription-manager RHSA-2017:0698-01
Summary:The remote host is missing an update for the 'subscription-manager'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'subscription-manager'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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.
