    description From Red Hat Security Advisory 2014:0743 : Updated qemu-kvm packages that fix multiple security issues and two bugs are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having Moderate 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. KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm package provides the user-space component for running virtual machines using KVM. Multiple buffer overflow, input validation, and out-of-bounds write flaws were found in the way the virtio, virtio-net, virtio-scsi, and usb drivers of QEMU handled state loading after migration. A user able to alter the savevm data (either on the disk or over the wire during migration) could use either of these flaws to corrupt QEMU process memory on the (destination) host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2013-4148, CVE-2013-4151, CVE-2013-4535, CVE-2013-4536, CVE-2013-4541, CVE-2013-4542, CVE-2013-6399, CVE-2014-0182, CVE-2014-3461) An out-of-bounds memory access flaw was found in the way QEMU's IDE device driver handled the execution of SMART EXECUTE OFFLINE commands. 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-2014-2894) The CVE-2013-4148, CVE-2013-4151, CVE-2013-4535, CVE-2013-4536, CVE-2013-4541, CVE-2013-4542, CVE-2013-6399, CVE-2014-0182, and CVE-2014-3461 issues were discovered by Michael S. Tsirkin of Red Hat, Anthony Liguori, and Michael Roth. This update also fixes the following bugs : * Previously, under certain circumstances, libvirt failed to start guests which used a non-zero PCI domain and SR-IOV Virtual Functions (VFs), and returned the following error message : Can't assign device inside non-zero PCI segment as this KVM module doesn't support it. This update fixes this issue and guests using the aforementioned configuration no longer fail to start. (BZ#1099941) * Due to an incorrect initialization of the cpus_sts bitmap, which holds the enablement status of a vCPU, libvirt could fail to start a guest with an unusual vCPU topology (for example, a guest with three cores and two sockets). With this update, the initialization of cpus_sts has been corrected, and libvirt no longer fails to start the aforementioned guests. (BZ#1100575) All qemu-kvm users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 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.

This update also fixes the following bugs : * Previously, under certain circumstances, libvirt failed to start guests which used a non-zero PCI domain and SR-IOV Virtual Functions (VFs), and returned the following error message : Can't assign device inside non-zero PCI segment as this KVM module doesn't support it. This update fixes this issue and guests using the aforementioned configuration no longer fail to start. (BZ#1099941) * Due to an incorrect initialization of the cpus_sts bitmap, which holds the enablement status of a vCPU, libvirt could fail to start a guest with an unusual vCPU topology (for example, a guest with three cores and two sockets). With this update, the initialization of cpus_sts has been corrected, and libvirt no longer fails to start the aforementioned guests. (BZ#1100575) All qemu-kvm users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 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.

    NASL id ORACLELINUX_ELSA-2014-0704.NASL
    description From Red Hat Security Advisory 2014:0704 : Updated qemu-kvm packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 7. 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. KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm packages provide a user-space component to run virtual machines using KVM. An out-of-bounds memory access flaw was found in the way QEMU's IDE device driver handled the execution of SMART EXECUTE OFFLINE commands. 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-2014-2894) This update also fixes the following bugs : * Prior to this update, a bug in the migration code caused the following error on specific machine types: after a Red Hat Enterprise Linux 6.5 guest was migrated from a Red Hat Enterprise Linux 6.5 host to a Red Hat Enterprise Linux 7.0 host and then restarted, the boot failed and the guest automatically restarted. Thus, the guest entered an endless loop. With this update, the migration code has been fixed and the Red Hat Enterprise Linux 6.5 guests migrated in the aforementioned scenario now boot properly. (BZ#1091322) * Due to a regression bug in the iSCSI driver, the qemu-kvm process terminated unexpectedly with a segmentation fault when the 'write same' command was executed in guest mode under the iSCSI protocol. This update fixes the regression and the 'write same' command now functions in guest mode under iSCSI as intended. (BZ#1090978) * Due to a mismatch in interrupt request (IRQ) routing, migration of a Red Hat Enterprise Linux 6.5 guest from a Red Hat Enterprise Linux 6.5 host to a Red Hat Enterprise Linux 7.0 host could produce a call trace. This happened if memory ballooning and a Universal Host Control Interface (UHCI) device were used at the same time on certain machine types. With this patch, the IRQ routing mismatch has been amended and the described migration now proceeds as expected. (BZ#1090981) * Previously, an internal error prevented KVM from executing a CPU hot plug on a Red Hat Enterprise Linux 7 guest running on a Red Hat Enterprise Linux 7 host. This update addresses the internal error and CPU hot plugging in the described scenario now functions correctly. (BZ#1094820) All qemu-kvm users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 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.
