The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3449-1 advisory.

    George Shuklin discovered that OpenStack Nova incorrectly handled the migration process. A remote     authenticated user could use this issue to consume resources, resulting in a denial of service.
    (CVE-2015-3241)

    George Shuklin and Tushar Patil discovered that OpenStack Nova incorrectly handled deleting instances. A     remote authenticated user could use this issue to consume disk resources, resulting in a denial of     service. (CVE-2015-3280)

    It was discovered that OpenStack Nova incorrectly limited qemu-img calls. A remote authenticated user     could use this issue to consume resources, resulting in a denial of service. (CVE-2015-5162)

    Matthew Booth discovered that OpenStack Nova incorrectly handled snapshots. A remote authenticated user     could use this issue to read arbitrary files. (CVE-2015-7548)

    Sreekumar S. and Suntao discovered that OpenStack Nova incorrectly applied security group changes. A     remote attacker could possibly use this issue to bypass intended restriction changes by leveraging an     instance that was running when the change was made. (CVE-2015-7713)

    Matt Riedemann discovered that OpenStack Nova incorrectly handled logging. A local attacker could possibly     use this issue to obtain sensitive information from log files. (CVE-2015-8749)

    Matthew Booth discovered that OpenStack Nova incorrectly handled certain qcow2 headers. A remote     authenticated user could possibly use this issue to read arbitrary files. (CVE-2016-2140)

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

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2016:2991 advisory.

    OpenStack Compute (nova) launches and schedules large networks of virtual machines, creating a redundant     and scalable cloud computing platform. Compute provides the software, control panels, and APIs required to     orchestrate a cloud, including running virtual machine instances and controlling access through users and     projects.

    OpenStack Block Storage (cinder) manages block storage mounting and the presentation of such mounted block     storage to instances. The backend physical storage can consist of local disks, or Fiber Channel, iSCSI,     and NFS mounts attached to Compute nodes. In addition, Block Storage supports volume backups, and     snapshots for temporary save and restore operations. Programatic management is available via Block     Storage's API.

    OpenStack Image Service (glance) provides discovery, registration, and delivery services for disk and     server images. The service provides the ability to copy or snapshot a server image, and immediately store     it away. Stored images can be used as a template to get new servers up and running quickly and more     consistently than installing a server operating system and individually configuring additional services.

    The following packages have been upgraded to a newer upstream version: openstack-nova (12.0.5), openstack-     cinder (7.0.3), openstack-glance (11.0.1). (BZ#1381466, BZ#1396263)

    Security Fix(es):

    * A resource vulnerability in the OpenStack Compute (nova), Block Storage (cinder), and Image (glance)     services was found in their use of qemu-img. An unprivileged user could consume as much as 4 GB of RAM on     the compute host by uploading a malicious image. This flaw could lead possibly to host out-of-memory     errors and negatively affect other running tenant instances. (CVE-2015-5162)

    This issue was discovered by Richard W.M. Jones (Red Hat).

    Bug Fix(es):

    * There is a known issue with Unicode string handling in the OSProfiler library. Consequently, the     creation of a Block Storage (cinder) snapshot will fail if it uses non-ASCII characters. With this update,     the OSProfiler library is not loaded unless it is specifically enabled in the cinder configuration. As a     result, the Unicode handling issue in OSProfiler is still present, and will result in the same failure if     OSProfiler is used, however it will be unlikely to occur in most cinder configurations. A more in-depth     resolution for this issue is not currently in scope. (BZ#1383899)

    (CVE-2015-5162)

    This issue was discovered by Richard W.M. Jones (Red Hat).

    Bug Fix(es):

    * qemu-img calls were unrestricted by ulimit. oslo.concurrency has been updated to add support for process     limits ('prlimit'), which is needed to fix the CVE-2015-5162 security vulnerability. (BZ#1383415)

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

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

  - The image parser in OpenStack Cinder 7.0.2 and 8.0.0 through 8.1.1; Glance before 11.0.1 and 12.0.0; and     Nova before 12.0.4 and 13.0.0 does not properly limit qemu-img calls, which might allow attackers to cause     a denial of service (memory and disk consumption) via a crafted disk image. (CVE-2015-5162)

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