The Python client in Apache Qpid before 2.2 does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - The Python client in Apache Qpid before 2.2 does not verify that the server hostname matches a domain name
    in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-
    the-middle attackers to spoof SSL servers via an arbitrary valid certificate. (CVE-2013-1909)

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

  - The Python client in Apache Qpid before 2.2 does not verify that the server hostname matches a domain name     in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-     the-middle attackers to spoof SSL servers via an arbitrary valid certificate. (CVE-2013-1909)

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

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2013:1024 advisory.

    Red Hat Enterprise MRG (Messaging, Realtime, and Grid) is a next-generation     IT infrastructure for enterprise computing. MRG offers increased     performance, reliability, interoperability, and faster computing for     enterprise customers.

    MRG Messaging is a high-speed reliable messaging distribution for Linux     based on AMQP (Advanced Message Queuing Protocol), an open protocol     standard for enterprise messaging that is designed to make mission critical     messaging widely available as a standard service, and to make enterprise     messaging interoperable across platforms, programming languages, and     vendors. MRG Messaging includes an AMQP 0-10 messaging broker; AMQP 0-10     client libraries for C++, Java JMS, and Python; as well as persistence     libraries and management tools.

    It was discovered that the Qpid Python client library for AMQP did not     properly perform TLS/SSL certificate validation of the remote server's     certificate, even when the 'ssl_trustfile' connection option was specified.
    A rogue server could use this flaw to conduct man-in-the-middle attacks,     possibly leading to the disclosure of sensitive information.
    (CVE-2013-1909)

    With this update, Python programs can instruct the library to validate     server certificates by specifying a path to a file containing trusted CA     certificates.

    This issue was discovered by Petr Matousek of the Red Hat MRG Messaging     team.

    This update also fixes multiple bugs. Documentation for these changes will     be available shortly from the Technical Notes document linked to in the     References section.

    All users of the Messaging capabilities of Red Hat Enterprise MRG 2.3 are     advised to upgrade to these updated packages, which resolve the issues     noted in the Red Hat Enterprise MRG 2 Technical Notes. After installing the     updated packages, stop the cluster by either running service qpidd stop     on all nodes, or qpid-cluster --all-stop on any one of the cluster nodes.
    Once stopped, restart the cluster with service qpidd start on all nodes     for the update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
