Updated qemu-kvm-rhev, qemu-kvm-rhev-tools, and qemu-img-rhev packages are 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.

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the user-space component for running virtual machines using KVM, in environments managed by Red Hat Enterprise Virtualization Manager.

A buffer overflow flaw was found in the way QEMU processed the SCSI 'REPORT LUNS' command when more than 256 LUNs were specified for a single SCSI target. A privileged guest user could use this flaw to corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2013-4344)

This issue was discovered by Asias He of Red Hat.

This update fixes the following bugs :

* In QMP monitor, if an attempt was made to create an image with the same file name as the backing file, an error was generated, but no message was displayed. Performing this action in QMP Monitor now generates the same error message as performing the action in HMP:
'Error: Trying to create an image with the same file name as the backing file'. (BZ#877240)

* QEMU I/O throttling has been disabled in Red Hat Enterprise Linux and is now only available enabled in the Red Hat Enterprise Virtualization QEMU package (qemu-kvm-rhev). (BZ#975468)

* When booting a guest machine, it would still boot when specifying iops and bps as a negative value, without displaying an error message.
This has been fixed so that if a negative value is used the guest does not boot and QEMU exits with the following message 'bps and iops values must be 0 or greater'. (BZ#987725)

* When booting a guest with QMP server, hot plug was failing. It can now do hotplug with QEMU I/O throttling including iops, iops_wr, iops_rd, bps, bps_wr, bps_rd inofs successfully. (BZ#987745)

* Due to a change in virtualization features, all fixes and errata related to Red Hat Enterprise Virtualization specific features, can only be posted to the Red Hat Enterprise Virtualization channel.
Therefore a Red Hat Enterprise Virtualization specific qemu-kvm (for RHEV-H-6.5.0 Errata) was developed. This meant that the qemu-kvm-rhev binary was mapped to a Red Had enterprise Virtualization channel, entitled to Red Hat Enterprise Virtualization customers, and disabled from the Red Hat Enterprise Linux channel. (BZ#997032)

* The qemu-kvm-rhev package now contains /usr/lib64/qemu, as this directory is where CEPH packages provide librbd to be used by QEMU at runtime. (BZ#999705)

* QEMU performed a core dump when iops.bps was set to a negative value. This has been fixed so that it no longer performs a core dump when a negative value is entered, instead an error message is displayed indicating the values must be zero of greater. (BZ#1001436)

* When running the 'rpm -V qemu-kvm-rhev' command, an error was generated stating there were unsatisfied dependencies. This has been fixed so there now are no unsatisfied dependencies and it executes correctly. (BZ#1010930)

In addition, this update adds the following enhancements :

* QEMU I/O throttling allows for finer control of the rate of I/O operations at the QEMU level, and is therefore independent of the underlying storage device. A similar feature can be created by using cgroups at the libvirt level, but cgroups is limited as it does not support some storage devices (such as image files over NFS) and throttles the whole virtual machine, including access to meta-data, while qemu I/O is more fine-grained. (BZ#956825)

* Patches were added to the QEMU block driver for accessing CEPH storage on qemu-kvm-rhev. However,this is not usable on its own, a librbd library still needs to be provided. The librbd library is not provided in Red Hat Enterprise Linux and will be handled by a third party source. (BZ#988079)

The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2014-016:01 advisory.

    KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware.
    Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual     machine has private virtualized hardware: a network card, disk, graphics adapter, etc.
    Security issues fixed with this release:
     CVE-2013-4344     Buffer overflow in the SCSI implementation in QEMU, as used in Xen, when a SCSI controller has more than     256 attached devices, allows local users to gain privileges via a small transfer buffer in a REPORT LUNS     command.
    Fixed bugs:
     Fixed smart card emulation with MS Windows guests versions XP, 2003 and 7.
     The page_l1_map() function now works properly when using KVM and could lead to segmentation faults or     other problems when calling page_l1_map(1 << 20) beyond the end of the l1_map array.
     Fixed I/O performance degradation.
     The qemu-img info command took a long time to respond when run immediately after creating an image with     very small non-standard cluster sizes (for example, 512 bytes). This has been fixed      Fixed a regression and live migration with the --copy-storage-all option now finishes successfully: no     more error: Unable to read from monitor: Connection reset by peer messages.
     qemu now supports opening VMWare ESX image files.
     Added support for VMDK version 3 images: qemu-img can now convert them.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

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

Several vulnerabilities were discovered in qemu, a fast processor emulator.

  - CVE-2013-4344     Buffer overflow in the SCSI implementation in QEMU, when     a SCSI controller has more than 256 attached devices,     allows local users to gain privileges via a small     transfer buffer in a REPORT LUNS command.

  - CVE-2014-2894     Off-by-one error in the cmd_smart function in the smart     self test in hw/ide/core.c in QEMU allows local users to     have unspecified impact via a SMART EXECUTE OFFLINE     command that triggers a buffer underflow and memory     corruption.

Updated qemu-kvm packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.

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.

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems that is built into the standard Red Hat Enterprise Linux kernel. The qemu-kvm packages form the user-space component for running virtual machines using KVM.

(CVE-2013-4344)

This issue was discovered by Asias He of Red Hat.

These updated qemu-kvm packages include numerous bug fixes and various enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.5 Technical Notes, linked to in the References, for information on the most significant of these changes.

All qemu-kvm users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements. After installing this update, shut down all running virtual machines. Once all virtual machines have shut down, start them again for this update to take effect.

The QEMU embedded within KVM received various security fixes.

Various issues in the block layer have been fixed :

  - A virtio security issue in config io space handling.
    (CVE-2013-2016)

  - A SCSI report LUNs buffer overflow. (CVE-2013-4344)

  - A buffer overflow in the QEMU USB stack. (CVE-2013-4541)

Several vulnerabilities were discovered in qemu-kvm, a full virtualization solution on x86 hardware.

  - CVE-2013-4344     Buffer overflow in the SCSI implementation in QEMU, when     a SCSI controller has more than 256 attached devices,     allows local users to gain privileges via a small     transfer buffer in a REPORT LUNS command.

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2013:1527 advisory.

    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 buffer overflow flaw was found in the way QEMU processed the SCSI REPORT     LUNS command when more than 256 LUNs were specified for a single SCSI     target. A privileged guest user could use this flaw to corrupt QEMU process     memory on the host, which could potentially result in arbitrary code     execution on the host with the privileges of the QEMU process.
    (CVE-2013-4344)

    Multiple flaws were found in the way Linux kernel handled HID (Human     Interface Device) reports. An attacker with physical access to the system     could use this flaw to crash the system or, potentially, escalate their     privileges on the system. (CVE-2013-2888, CVE-2013-2889, CVE-2013-2892)

    A flaw was found in the way the Python SSL module handled X.509 certificate     fields that contain a NULL byte. An attacker could potentially exploit this     flaw to conduct man-in-the-middle attacks to spoof SSL servers. Note that     to exploit this issue, an attacker would need to obtain a carefully crafted     certificate signed by an authority that the client trusts. (CVE-2013-4238)

    The default OpenSSH configuration made it easy for remote attackers to     exhaust unauthorized connection slots and prevent other users from being     able to log in to a system. This flaw has been addressed by enabling random     early connection drops by setting MaxStartups to 10:30:100 by default.
    For more information, refer to the sshd_config(5) man page. (CVE-2010-5107)

    The CVE-2013-4344 issue was discovered by Asias He 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-2013-1775, CVE-2013-2776, and CVE-2013-2777 (sudo issues)

    This update also fixes the following bug:

    * A previous version of the rhev-hypervisor6 package did not contain the     latest vhostmd package, which provides a metrics communication channel     between a host and its hosted virtual machines, allowing limited     introspection of host resource usage from within virtual machines. This has     been fixed, and rhev-hypervisor6 now includes the latest vhostmd package.
    (BZ#1026703)

    This update also contains the fixes from the following errata:

    * ovirt-node: https://rhn.redhat.com/errata/RHBA-2013-1528.html

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