Scroller Redhat
Recent patch for subscription-manager addresses vulnerabilities in Red Hat, mitigating risks of data leaks. Follow the guidelines to enhance your system's security.
An update for subscription-manager, subscription-manager-migration-data, and python-rhsm is now available for Red Hat Enterprise Linux 6

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

Summary

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.
