Summary
Red Hat Security Advisory: qemu-kvm-rhev, qemu-kvm-rhev-tools, qemu-img-rhev security and bug fix update
Notes
Topic
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.
Details
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)

Summary
Red Hat Security Advisory: qemu-kvm security, bug fix, and enhancement update
Notes
Topic
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.
Details
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.
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.
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.

Summary
Red Hat Security Advisory: rhev-hypervisor6 security and bug fix update
Notes
Topic
An updated rhev-hypervisor6 package that fixes multiple security issues and
one bug 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.
Details
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-2012-0786 and CVE-2012-0787 (augeas issues)
CVE-2013-1813 (busybox issue)
CVE-2013-0221, CVE-2013-0222, and CVE-2013-0223 (coreutils issues)
CVE-2012-4453 (dracut issue)
CVE-2013-4332, CVE-2013-0242, and CVE-2013-1914 (glibc issues)
CVE-2013-4387, CVE-2013-0343, CVE-2013-4345, CVE-2013-4591, CVE-2013-4592,
CVE-2012-6542, CVE-2013-3231, CVE-2013-1929, CVE-2012-6545, CVE-2013-1928,
CVE-2013-2164, CVE-2013-2234, and CVE-2013-2851 (kernel issues)
CVE-2013-4242 (libgcrypt issue)
CVE-2013-4419 (libguestfs issue)
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.

Common Vulnerability Scoring System (CVSS) base\nscores, which give detailed severity ratings, are available for each\nvulnerability from the CVE links in the References section.", "title": "Topic" }, { "category": "general", "text": "The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization\nHypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor\nis a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes\neverything necessary to run and manage virtual machines: a subset of the\nRed Hat Enterprise Linux operating environment and the Red Hat Enterprise\nVirtualization Agent.\n\nNote: Red Hat Enterprise Virtualization Hypervisor is only available for\nthe Intel 64 and AMD64 architectures with virtualization extensions.\n\nUpgrade Note: If you upgrade the Red Hat Enterprise Virtualization\nHypervisor through the 3.2 Manager administration portal, the Host may\nappear with the status of \"Install Failed\". If this happens, place the host\ninto maintenance mode, then activate it again to get the host back to an\n\"Up\" state.\n\nA buffer overflow flaw was found in the way QEMU processed the SCSI \"REPORT\nLUNS\" command when more than 256 LUNs were specified for a single SCSI\ntarget. A privileged guest user could use this flaw to corrupt QEMU process\nmemory on the host, which could potentially result in arbitrary code\nexecution on the host with the privileges of the QEMU process.\n(CVE-2013-4344)\n\nMultiple flaws were found in the way Linux kernel handled HID (Human\nInterface Device) reports. An attacker with physical access to the system\ncould use this flaw to crash the system or, potentially, escalate their\nprivileges on the system. (CVE-2013-2888, CVE-2013-2889, CVE-2013-2892)\n\nA flaw was found in the way the Python SSL module handled X.509 certificate\nfields that contain a NULL byte. An attacker could potentially exploit this\nflaw to conduct man-in-the-middle attacks to spoof SSL servers. Note that\nto exploit this issue, an attacker would need to obtain a carefully crafted\ncertificate signed by an authority that the client trusts. (CVE-2013-4238)\n\nThe default OpenSSH configuration made it easy for remote attackers to\nexhaust unauthorized connection slots and prevent other users from being\nable to log in to a system. This flaw has been addressed by enabling random\nearly connection drops by setting MaxStartups to 10:30:100 by default.\nFor more information, refer to the sshd_config(5) man page. (CVE-2010-5107)\n\nThe CVE-2013-4344 issue was discovered by Asias He of Red Hat.\n\nThis updated package provides updated components that include fixes for\nvarious security issues. These issues have no security impact on Red Hat\nEnterprise Virtualization Hypervisor itself, however. The security fixes\nincluded in this update address the following CVE numbers:\n\nCVE-2012-0786 and CVE-2012-0787 (augeas issues)\n\nCVE-2013-1813 (busybox issue)\n\nCVE-2013-0221, CVE-2013-0222, and CVE-2013-0223 (coreutils issues)\n\nCVE-2012-4453 (dracut issue)\n\nCVE-2013-4332, CVE-2013-0242, and CVE-2013-1914 (glibc issues)\n\nCVE-2013-4387, CVE-2013-0343, CVE-2013-4345, CVE-2013-4591, CVE-2013-4592,\nCVE-2012-6542, CVE-2013-3231, CVE-2013-1929, CVE-2012-6545, CVE-2013-1928,\nCVE-2013-2164, CVE-2013-2234, and CVE-2013-2851 (kernel issues)\n\nCVE-2013-4242 (libgcrypt issue)\n\nCVE-2013-4419 (libguestfs issue)\n\nCVE-2013-1775, CVE-2013-2776, and CVE-2013-2777 (sudo issues)\n\nThis update also fixes the following bug:\n\n* A previous version of the rhev-hypervisor6 package did not contain the\nlatest vhostmd package, which provides a \"metrics communication channel\"\nbetween a host and its hosted virtual machines, allowing limited\nintrospection of host resource usage from within virtual machines. This has\nbeen fixed, and rhev-hypervisor6 now includes the latest vhostmd package.\n(BZ#1026703)\n\nThis update also contains the fixes from the following errata:\n\n* ovirt-node: https://rhn.redhat.com/errata/RHBA-2013-1528.html\n\nUsers of the Red Hat Enterprise Virtualization Hypervisor are advised to\nupgrade to this updated package, which corrects these issues.", "title": "Details" }, { "category": "legal_disclaimer", "text": "This content is licensed under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/).
