libvirt was updated to fix 2 security issues :

CVE-2013-4311: Add support for using 3-arg pkcheck syntax for process, which previously could be used for race conditions to gain privileges.

CVE-2013-4296: Fix crash in remoteDispatchDomainMemoryStats

Updated libvirt packages that fix two security issues and several bugs are now available for Red Hat Enterprise Linux 6.

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.

The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems.

libvirt invokes the PolicyKit pkcheck utility to handle authorization.
A race condition was found in the way libvirt used this utility, allowing a local user to bypass intended PolicyKit authorizations or execute arbitrary commands with root privileges. (CVE-2013-4311)

Note: With this update, libvirt has been rebuilt to communicate with PolicyKit via a different API that is not vulnerable to the race condition. The polkit RHSA-2013:1270 advisory must also be installed to fix the CVE-2013-4311 issue.

An invalid free flaw was found in libvirtd's remoteDispatchDomainMemoryStats function. An attacker able to establish a read-only connection to libvirtd could use this flaw to crash libvirtd. (CVE-2013-4296)

The CVE-2013-4296 issue was discovered by Daniel P. Berrange of Red Hat.

This update also fixes the following bugs :

* Prior to this update, the libvirtd daemon leaked memory in the virCgroupMoveTask() function. A fix has been provided which prevents libvirtd from incorrect management of memory allocations. (BZ#984556)

* Previously, the libvirtd daemon was accessing one byte before the array in the virCgroupGetValueStr() function. This bug has been fixed and libvirtd now stays within the array bounds. (BZ#984561)

* When migrating, libvirtd leaked the migration URI (Uniform Resource Identifier) on destination. A patch has been provided to fix this bug and the migration URI is now freed correctly. (BZ#984578)

* Updating a network interface using virDomainUpdateDeviceFlags API failed when a boot order was set for that interface. The update failed even if the boot order was set in the provided device XML. The virDomainUpdateDeviceFlags API has been fixed to correctly parse the boot order specification from the provided device XML and updating network interfaces with boot orders now works as expected.
(BZ#1003934)

Users of libvirt are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, libvirtd will be restarted automatically.

- Rebased to version 0.10.2.8

    - CVE-2013-4311: Insecure polkit usage (bz #1009539, bz       #1005332)

    - CVE-2013-4291: Supplementary groups handling (bz       #1006509, bz #1006511)

libvirt was updated to fix security issues and bugs :

Security issues fixed: CVE-2013-4311: Add support for using 3-arg pkcheck syntax for process to avoid race conditions.

CVE-2013-4296: Fix a crash (denial of service) in remoteDispatchDomainMemoryStats

CVE-2013-5651: Fix virBitmapParse to avoid access beyond bounds of array (denial of service crash).

Also bugs were fixed :

An updated rhev-hypervisor6 package that fixes one security issue and various bugs 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.

Upgrade Note: If you upgrade the Red Hat Enterprise Virtualization Hypervisor through the 3.2 Manager administration portal, the Host may appear with the status of 'Install Failed'. If this happens, place the host into maintenance mode, then activate it again to get the host back to an 'Up' state

A stack-based buffer overflow flaw was found in the way the reds_handle_ticket() function in the spice-server library handled decryption of ticket data provided by the client. A remote attacker able to initiate a SPICE connection to the guest could use this flaw to crash the guest. (CVE-2013-4282)

This issue was discovered by Tomas Jamrisko of Red Hat.

This updated package provides updated components that include fixes for various security issues. These issues have no security impact on Red Hat Enterprise Virtualization Hypervisor itself, however. The security fixes included in this update address the following CVE numbers :

CVE-2013-4162 and CVE-2013-4299 (kernel issues)

CVE-2013-4296 and CVE-2013-4311 (libvirt issues)

CVE-2013-4288 (polkit issue)

This update also contains the fixes from the following advisories :

* vdsm: https://rhn.redhat.com/errata/RHBA-2013-1462.html

* ovirt-node: https://rhn.redhat.com/errata/RHBA-2013-1461.html

Users of the Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which corrects these issues.

The remote host is affected by the vulnerability described in GLSA-201412-04 (libvirt: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in libvirt. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker may be able to cause a Denial of Service or cause       information leakage. A local attacker may be able to escalate privileges,       cause a Denial of Service or possibly execute arbitrary code.
  Workaround :

    There is no known workaround at this time.
