Summary
Red Hat Security Advisory: rhev-hypervisor security and bug fix update
Notes
Topic
Updated rhev-hypervisor packages that fix multiple security issues and two
bugs are 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-hypervisor 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.
It was found that the libspice component of QEMU-KVM on the host did not
validate all pointers provided from a guest system's QXL graphics card
driver. A privileged guest user could use this flaw to cause the host to
dereference an invalid pointer, causing the guest to crash (denial of
service) or, possibly, resulting in the privileged guest user escalating
their privileges on the host. (CVE-2010-0428)
It was found that the libspice component of QEMU-KVM on the host could be
forced to perform certain memory management operations on memory addresses
controlled by a guest. A privileged guest user could use this flaw to crash
the guest (denial of service) or, possibly, escalate their privileges on
the host. (CVE-2010-0429)
It was found that QEMU-KVM on the host did not validate all pointers
provided from a guest system's QXL graphics card driver. A privileged guest
user could use this flaw to cause the host to dereference an invalid
pointer, causing the guest to crash (denial of service) or, possibly,
resulting in the privileged guest user escalating their privileges on the
host. (CVE-2010-0431)
A flaw was found in QEMU-KVM, allowing the guest some control over the
index used to access the callback array during sub-page MMIO
initialization. A privileged guest user could use this flaw to crash the
guest (denial of service) or, possibly, escalate their privileges on the
host. (CVE-2010-2784)
A NULL pointer dereference flaw was found when Red Hat Enterprise
Virtualization Hypervisor was run on a system that has a processor with the
Intel VT-x extension enabled. A privileged guest user could use this flaw
to trick the host into emulating a certain instruction, which could crash
the host (denial of service). (CVE-2010-0435)
A flaw was found in the way VDSM accepted SSL connections. An attacker
could trigger this flaw by creating a crafted SSL connection to VDSM,
preventing VDSM from accepting SSL connections from other users.
(CVE-2010-2811)
These updated packages provide updated components that include fixes for
security issues; however, these issues have no security impact for Red Hat
Enterprise Virtualization Hypervisor. These fixes are for avahi issues
CVE-2009-0758 and CVE-2010-2244; freetype issues CVE-2010-1797,
CVE-2010-2498, CVE-2010-2499, CVE-2010-2500, CVE-2010-2519, CVE-2010-2527,
and CVE-2010-2541; kernel issues CVE-2010-1084, CVE-2010-2066,
CVE-2010-2070, CVE-2010-2226, CVE-2010-2248, CVE-2010-2521, and
CVE-2010-2524; and openldap issues CVE-2010-0211 and CVE-2010-0212.
These updated rhev-hypervisor packages also fix two bugs. Documentation for
these bug fixes will be available shortly from
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Virtualization_for_Servers/2.2/html/Technical_Notes/index.html
As Red Hat Enterprise Virtualization Hypervisor is based on KVM, the bug
fixes from the KVM update RHSA-2010:0627 have been included in this update.
Also included are the bug fixes from the VDSM update RHSA-2010:0628.
KVM: https://rhn.redhat.com/errata/RHSA-2010-0627.html
VDSM: https://rhn.redhat.com/errata/RHSA-2010-0628.html
Users of Red Hat Enterprise Virtualization Hypervisor are advised to
upgrade to these updated rhev-hypervisor packages, which resolve these
issues.

Summary
Red Hat Security Advisory: vdsm22 security and bug fix update
Notes
Topic
Updated vdsm22 packages that fix one security issue and multiple bugs are
now available for Red Hat Enterprise Linux 5.5.
The Red Hat Security Response Team has rated this update as having moderate
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
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 hosts.
Note: This update has been tested and is supported on Red Hat Enterprise
Linux 5.5 (with all appropriate post-GA 5.5-specific updates).
A flaw was found in the way VDSM accepted SSL connections. An attacker
could trigger this flaw by creating a crafted SSL connection to VDSM,
preventing VDSM from accepting SSL connections from other users.
(CVE-2010-2811)
These updated vdsm22 packages also fix the following bugs:
* suspend-to-file hibernation failed for huge guests due to the migration
and hibernation constant values being too short for huge guests. This
update makes the timeouts proportional to guest RAM size, thus allowing
suspension of huge guests in all cases except where storage is unbearably
slow. (BZ#601275)
* under certain circumstances, restarting a VDSM that was being used as a
Storage Pool Manager killed all system processes on the host. With this
update, stopping VDSM is ensured to kill only the processes that it
started, and the VDSM SIGTERM handler is not run concurrently. With these
changes, all processes on the host are no longer killed when VDSM is
restarted. (BZ#614849)
* when VDSM was requested to "start in paused mode", it incorrectly
reported virtual guest state as "WaitForLaunch" instead of "Paused", which
led to the virtual guest being inaccessible from Red Hat Enterprise
Virtualization Manager. With this update, VDSM reports such virtual guests
as "Paused", and users are able to connect to the virtual guest display.
(BZ#616464)
Red Hat Enterprise Virtualization Manager 2.2 users with Red Hat Enterprise
Linux hosts should install these updated packages, which resolve these
issues. Alternatively, Red Hat Enterprise Virtualization Manager can
install the new package automatically.

Summary
Red Hat Security Advisory: vdsm22 security and bug fix update
Notes
Topic
Updated vdsm22 packages that fix one security issue and multiple bugs are
now available for Red Hat Enterprise Linux 5.5.
The Red Hat Security Response Team has rated this update as having moderate
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
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 hosts.
Note: This update has been tested and is supported on Red Hat Enterprise
Linux 5.5 (with all appropriate post-GA 5.5-specific updates).
A flaw was found in the way VDSM accepted SSL connections. An attacker
could trigger this flaw by creating a crafted SSL connection to VDSM,
preventing VDSM from accepting SSL connections from other users.
(CVE-2010-2811)
These updated vdsm22 packages also fix the following bugs:
* suspend-to-file hibernation failed for huge guests due to the migration
and hibernation constant values being too short for huge guests. This
update makes the timeouts proportional to guest RAM size, thus allowing
suspension of huge guests in all cases except where storage is unbearably
slow. (BZ#601275)
* under certain circumstances, restarting a VDSM that was being used as a
Storage Pool Manager killed all system processes on the host. With this
update, stopping VDSM is ensured to kill only the processes that it
started, and the VDSM SIGTERM handler is not run concurrently. With these
changes, all processes on the host are no longer killed when VDSM is
restarted. (BZ#614849)
* when VDSM was requested to "start in paused mode", it incorrectly
reported virtual guest state as "WaitForLaunch" instead of "Paused", which
led to the virtual guest being inaccessible from Red Hat Enterprise
Virtualization Manager. With this update, VDSM reports such virtual guests
as "Paused", and users are able to connect to the virtual guest display.
(BZ#616464)
Red Hat Enterprise Virtualization Manager 2.2 users with Red Hat Enterprise
Linux hosts should install these updated packages, which resolve these
issues. Alternatively, Red Hat Enterprise Virtualization Manager can
install the new package automatically.

Summary
Red Hat Security Advisory: rhev-hypervisor security and bug fix update
Notes
Topic
Updated rhev-hypervisor packages that fix multiple security issues and two
bugs are 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-hypervisor 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.
It was found that the libspice component of QEMU-KVM on the host did not
validate all pointers provided from a guest system's QXL graphics card
driver. A privileged guest user could use this flaw to cause the host to
dereference an invalid pointer, causing the guest to crash (denial of
service) or, possibly, resulting in the privileged guest user escalating
their privileges on the host. (CVE-2010-0428)
It was found that the libspice component of QEMU-KVM on the host could be
forced to perform certain memory management operations on memory addresses
controlled by a guest. A privileged guest user could use this flaw to crash
the guest (denial of service) or, possibly, escalate their privileges on
the host. (CVE-2010-0429)
It was found that QEMU-KVM on the host did not validate all pointers
provided from a guest system's QXL graphics card driver. A privileged guest
user could use this flaw to cause the host to dereference an invalid
pointer, causing the guest to crash (denial of service) or, possibly,
resulting in the privileged guest user escalating their privileges on the
host. (CVE-2010-0431)
A flaw was found in QEMU-KVM, allowing the guest some control over the
index used to access the callback array during sub-page MMIO
initialization. A privileged guest user could use this flaw to crash the
guest (denial of service) or, possibly, escalate their privileges on the
host. (CVE-2010-2784)
A NULL pointer dereference flaw was found when Red Hat Enterprise
Virtualization Hypervisor was run on a system that has a processor with the
Intel VT-x extension enabled. A privileged guest user could use this flaw
to trick the host into emulating a certain instruction, which could crash
the host (denial of service). (CVE-2010-0435)
A flaw was found in the way VDSM accepted SSL connections. An attacker
could trigger this flaw by creating a crafted SSL connection to VDSM,
preventing VDSM from accepting SSL connections from other users.
(CVE-2010-2811)
These updated packages provide updated components that include fixes for
security issues; however, these issues have no security impact for Red Hat
Enterprise Virtualization Hypervisor. These fixes are for avahi issues
CVE-2009-0758 and CVE-2010-2244; freetype issues CVE-2010-1797,
CVE-2010-2498, CVE-2010-2499, CVE-2010-2500, CVE-2010-2519, CVE-2010-2527,
and CVE-2010-2541; kernel issues CVE-2010-1084, CVE-2010-2066,
CVE-2010-2070, CVE-2010-2226, CVE-2010-2248, CVE-2010-2521, and
CVE-2010-2524; and openldap issues CVE-2010-0211 and CVE-2010-0212.
These updated rhev-hypervisor packages also fix two bugs. Documentation for
these bug fixes will be available shortly from
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Virtualization_for_Servers/2.2/html/Technical_Notes/index.html
As Red Hat Enterprise Virtualization Hypervisor is based on KVM, the bug
fixes from the KVM update RHSA-2010:0627 have been included in this update.
Also included are the bug fixes from the VDSM update RHSA-2010:0628.
KVM: https://rhn.redhat.com/errata/RHSA-2010-0627.html
VDSM: https://rhn.redhat.com/errata/RHSA-2010-0628.html
Users of Red Hat Enterprise Virtualization Hypervisor are advised to
upgrade to these updated rhev-hypervisor packages, which resolve these
issues.

(CVE-2010-2784)\n\nA NULL pointer dereference flaw was found when Red Hat Enterprise\nVirtualization Hypervisor was run on a system that has a processor with the\nIntel VT-x extension enabled. A privileged guest user could use this flaw\nto trick the host into emulating a certain instruction, which could crash\nthe host (denial of service). (CVE-2010-0435)\n\nA flaw was found in the way VDSM accepted SSL connections. An attacker\ncould trigger this flaw by creating a crafted SSL connection to VDSM,\npreventing VDSM from accepting SSL connections from other users.\n(CVE-2010-2811)\n\nThese updated packages provide updated components that include fixes for\nsecurity issues; however, these issues have no security impact for Red Hat\nEnterprise Virtualization Hypervisor.

Summary
Red Hat Security Advisory: vdsm22 security and bug fix update
Notes
Topic
Updated vdsm22 packages that fix one security issue and multiple bugs are
now available for Red Hat Enterprise Linux 5.5.
The Red Hat Security Response Team has rated this update as having moderate
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
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 hosts.
Note: This update has been tested and is supported on Red Hat Enterprise
Linux 5.5 (with all appropriate post-GA 5.5-specific updates).
A flaw was found in the way VDSM accepted SSL connections. An attacker
could trigger this flaw by creating a crafted SSL connection to VDSM,
preventing VDSM from accepting SSL connections from other users.
(CVE-2010-2811)
These updated vdsm22 packages also fix the following bugs:
* suspend-to-file hibernation failed for huge guests due to the migration
and hibernation constant values being too short for huge guests. This
update makes the timeouts proportional to guest RAM size, thus allowing
suspension of huge guests in all cases except where storage is unbearably
slow. (BZ#601275)
* under certain circumstances, restarting a VDSM that was being used as a
Storage Pool Manager killed all system processes on the host. With this
update, stopping VDSM is ensured to kill only the processes that it
started, and the VDSM SIGTERM handler is not run concurrently. With these
changes, all processes on the host are no longer killed when VDSM is
restarted. (BZ#614849)
* when VDSM was requested to "start in paused mode", it incorrectly
reported virtual guest state as "WaitForLaunch" instead of "Paused", which
led to the virtual guest being inaccessible from Red Hat Enterprise
Virtualization Manager. With this update, VDSM reports such virtual guests
as "Paused", and users are able to connect to the virtual guest display.
(BZ#616464)
Red Hat Enterprise Virtualization Manager 2.2 users with Red Hat Enterprise
Linux hosts should install these updated packages, which resolve these
issues. Alternatively, Red Hat Enterprise Virtualization Manager can
install the new package automatically.

Summary
Red Hat Security Advisory: rhev-hypervisor security and bug fix update
Notes
Topic
Updated rhev-hypervisor packages that fix multiple security issues and two
bugs are 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-hypervisor 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.
It was found that the libspice component of QEMU-KVM on the host did not
validate all pointers provided from a guest system's QXL graphics card
driver. A privileged guest user could use this flaw to cause the host to
dereference an invalid pointer, causing the guest to crash (denial of
service) or, possibly, resulting in the privileged guest user escalating
their privileges on the host. (CVE-2010-0428)
It was found that the libspice component of QEMU-KVM on the host could be
forced to perform certain memory management operations on memory addresses
controlled by a guest. A privileged guest user could use this flaw to crash
the guest (denial of service) or, possibly, escalate their privileges on
the host. (CVE-2010-0429)
It was found that QEMU-KVM on the host did not validate all pointers
provided from a guest system's QXL graphics card driver. A privileged guest
user could use this flaw to cause the host to dereference an invalid
pointer, causing the guest to crash (denial of service) or, possibly,
resulting in the privileged guest user escalating their privileges on the
host. (CVE-2010-0431)
A flaw was found in QEMU-KVM, allowing the guest some control over the
index used to access the callback array during sub-page MMIO
initialization. A privileged guest user could use this flaw to crash the
guest (denial of service) or, possibly, escalate their privileges on the
host. (CVE-2010-2784)
A NULL pointer dereference flaw was found when Red Hat Enterprise
Virtualization Hypervisor was run on a system that has a processor with the
Intel VT-x extension enabled. A privileged guest user could use this flaw
to trick the host into emulating a certain instruction, which could crash
the host (denial of service). (CVE-2010-0435)
A flaw was found in the way VDSM accepted SSL connections. An attacker
could trigger this flaw by creating a crafted SSL connection to VDSM,
preventing VDSM from accepting SSL connections from other users.
(CVE-2010-2811)
These updated packages provide updated components that include fixes for
security issues; however, these issues have no security impact for Red Hat
Enterprise Virtualization Hypervisor. These fixes are for avahi issues
CVE-2009-0758 and CVE-2010-2244; freetype issues CVE-2010-1797,
CVE-2010-2498, CVE-2010-2499, CVE-2010-2500, CVE-2010-2519, CVE-2010-2527,
and CVE-2010-2541; kernel issues CVE-2010-1084, CVE-2010-2066,
CVE-2010-2070, CVE-2010-2226, CVE-2010-2248, CVE-2010-2521, and
CVE-2010-2524; and openldap issues CVE-2010-0211 and CVE-2010-0212.
These updated rhev-hypervisor packages also fix two bugs. Documentation for
these bug fixes will be available shortly from
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Virtualization_for_Servers/2.2/html/Technical_Notes/index.html
As Red Hat Enterprise Virtualization Hypervisor is based on KVM, the bug
fixes from the KVM update RHSA-2010:0627 have been included in this update.
Also included are the bug fixes from the VDSM update RHSA-2010:0628.
KVM: https://rhn.redhat.com/errata/RHSA-2010-0627.html
VDSM: https://rhn.redhat.com/errata/RHSA-2010-0628.html
Users of Red Hat Enterprise Virtualization Hypervisor are advised to
upgrade to these updated rhev-hypervisor packages, which resolve these
issues.
