The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The Subscription Manager package (aka subscription-manager) before 1.17.7-1 for Candlepin uses weak     permissions (755) for subscription-manager cache directories, which allows local users to obtain sensitive     information by reading files in the directories. (CVE-2016-4455)

Note that Nessus relies on the presence of the package as reported by the vendor.

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) :

* 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.

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)

According to the version of the subscription-manager, python-rhsm packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

* 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.
