The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2012:1508 advisory.

    VDSM is a management module that serves as a Red Hat Enterprise     Virtualization Manager agent on Red Hat Enterprise Virtualization     Hypervisor or Red Hat Enterprise Linux 6.3 hosts.

    A flaw was found in the way Red Hat Enterprise Linux hosts were added to     the Red Hat Enterprise Virtualization environment. The Python scripts     needed to configure the host for Red Hat Enterprise Virtualization were     stored in the /tmp/ directory and could be pre-created by an attacker. A     local, unprivileged user on the host to be added to the Red Hat Enterprise     Virtualization environment could use this flaw to escalate their     privileges. This update provides the VDSM part of the fix. The     RHSA-2012:1506 Red Hat Enterprise Virtualization Manager update must also     be installed to completely fix this issue. (CVE-2012-0860)

    A flaw was found in the way Red Hat Enterprise Linux and Red Hat Enterprise     Virtualization Hypervisor hosts were added to the Red Hat Enterprise     Virtualization environment. The Python scripts needed to configure the host     for Red Hat Enterprise Virtualization were downloaded in an insecure way,     that is, without properly validating SSL certificates during HTTPS     connections. An attacker on the local network could use this flaw to     conduct a man-in-the-middle attack, potentially gaining root access to the     host being added to the Red Hat Enterprise Virtualization environment. This     update provides the VDSM part of the fix. The RHSA-2012:1506 Red Hat     Enterprise Virtualization Manager update must also be installed to     completely fix this issue. (CVE-2012-0861)

    The CVE-2012-0860 and CVE-2012-0861 issues were discovered by Red Hat.

    In addition to resolving the above security issues these updated VDSM     packages fix various bugs, and add various enhancements.

    Documentation for these bug fixes and enhancements is available in the     Technical Notes:

    https://access.redhat.com/knowledge/docs/en-     US/Red_Hat_Enterprise_Virtualization/3.1/html/Technical_Notes/index.html

    All users who require VDSM are advised to install these updated packages     which resolve these security issues, fix these bugs, and add these     enhancements.

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

An updated rhev-hypervisor6 package that fixes one security issue, various bugs, and adds enhancements is now available.

The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent.

Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions.

A flaw was found in the way Red Hat Enterprise Virtualization Hypervisor hosts were added to the Red Hat Enterprise Virtualization environment. The Python scripts needed to configure the host for Red Hat Enterprise Virtualization were downloaded in an insecure way, that is, without properly validating SSL certificates during HTTPS connections.

Red Hat Enterprise Virtualization Manager 3.1 is now available.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Red Hat Enterprise Virtualization Manager is a visual tool for centrally managing collections of virtual servers running Red Hat Enterprise Linux and Microsoft Windows. This package also includes the Red Hat Enterprise Virtualization Manager API, a set of scriptable commands that give administrators the ability to perform queries and operations on Red Hat Enterprise Virtualization Manager.

A flaw was found in the way Red Hat Enterprise Linux hosts were added to the Red Hat Enterprise Virtualization environment. The Python scripts needed to configure the host for Red Hat Enterprise Virtualization were stored in the '/tmp/' directory and could be pre-created by an attacker. A local, unprivileged user on the host to be added to the Red Hat Enterprise Virtualization environment could use this flaw to escalate their privileges. This update provides the Red Hat Enterprise Virtualization Manager part of the fix. The RHSA-2012:1508 VDSM update (Red Hat Enterprise Linux hosts) must also be installed to completely fix this issue. (CVE-2012-0860)

A flaw was found in the way Red Hat Enterprise Linux and Red Hat Enterprise Virtualization Hypervisor hosts were added to the Red Hat Enterprise Virtualization environment. The Python scripts needed to configure the host for Red Hat Enterprise Virtualization were downloaded in an insecure way, that is, without properly validating SSL certificates during HTTPS connections. An attacker on the local network could use this flaw to conduct a man-in-the-middle attack, potentially gaining root access to the host being added to the Red Hat Enterprise Virtualization environment. This update provides the Red Hat Enterprise Virtualization Manager part of the fix. The RHSA-2012:1508 VDSM update (Red Hat Enterprise Linux hosts) or RHSA-2012:1505 rhev-hypervisor6 update (Red Hat Enterprise Virtualization Hypervisor hosts) must also be installed to completely fix this issue. (CVE-2012-0861)

It was found that under certain conditions, Red Hat Enterprise Virtualization Manager would fail to lock the screen on a virtual machine between SPICE (Simple Protocol for Independent Computing Environments) sessions. A user with access to a virtual machine in Red Hat Enterprise Virtualization Manager could potentially exploit this flaw to gain access to another user's unlocked desktop session.
(CVE-2011-4316)

It was found that Red Hat Enterprise Virtualization Manager did not correctly pass wipe-after-delete when moving disks between storage domains. This resulted in such disks not being securely deleted as expected, potentially leading to information disclosure.
(CVE-2012-5516)

A flaw was found in the way the Red Hat Enterprise Virtualization Manager back end checked the privileges of users making requests via the SOAP and GWT APIs. An authenticated attacker able to issue queries against Red Hat Enterprise Virtualization Manager could use this flaw to query data that they should not have access to. (CVE-2012-2696)

These issues were discovered by Red Hat.

In addition to resolving the above security issues these updated Red Hat Enterprise Virtualization Manager packages fix various bugs, and add various enhancements.

Documentation for these bug fixes and enhancements is available in the Technical Notes :
