"2023-01-11T14:49:24", "description": "Updated qemu-kvm-rhev packages that fix two security issues and three bugs are now available for Red Hat Enterprise Virtualization.\n\nRed Hat Product Security 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.\n\nKVM (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.\n\nA use-after-free flaw was found in the way QEMU's IDE AHCI emulator processed certain AHCI Native Command Queuing (NCQ) AIO commands. A privileged guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-1568)\n\nAn out-of-bounds read/write flaw was discovered in the way QEMU's Firmware Configuration device emulation processed certain firmware configurations. A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process.\n(CVE-2016-1714)\n\nRed Hat would like to thank Qinghao Tang of Qihoo 360 Marvel Team for reporting the CVE-2016-1568 issue, and Donghai Zhu of Alibaba for reporting the CVE-2016-1714 issue.\n\nThis update also fixes the following bugs :\n\n* Incorrect handling of the last sector of an image file could trigger an assertion failure in qemu-img. This update changes the handling of the last sector, and no assertion failure occurs. (BZ#1299345)\n\n* Previously, rebooting a guest after multiple memory hot-plugs in some cases caused the qemu-kvm process to terminate unexpectedly, and the reboot to fail. This update fixes the problem, and guests with hot-plugged memory reboot successfully.

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.\n\nKVM (Kernel-based Virtual Machine) is a full virtualization solution\nfor Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package\nprovides the user-space component for running virtual machines using\nKVM.\n\nA use-after-free flaw was found in the way QEMU's IDE AHCI emulator\nprocessed certain AHCI Native Command Queuing (NCQ) AIO commands. A\nprivileged guest user could use this flaw to crash the QEMU process\ninstance or, potentially, execute arbitrary code on the host with\nprivileges of the QEMU process. (CVE-2016-1568)\n\nAn out-of-bounds read/write flaw was discovered in the way QEMU's\nFirmware Configuration device emulation processed certain firmware\nconfigurations. A privileged (CAP_SYS_RAWIO) guest user could use this\nflaw to crash the QEMU process instance or, potentially, execute\narbitrary code on the host with privileges of the QEMU process.\n(CVE-2016-1714)\n\nRed Hat would like to thank Qinghao Tang of Qihoo 360 Marvel Team for\nreporting the CVE-2016-1568 issue, and Donghai Zhu of Alibaba for\nreporting the CVE-2016-1714 issue.\n\nThis update also fixes the following bugs :\n\n* Incorrect handling of the last sector of an image file could trigger\nan assertion failure in qemu-img. This update changes the handling of\nthe last sector, and no assertion failure occurs. (BZ#1299345)\n\n* Previously, rebooting a guest after multiple memory hot-plugs in\nsome cases caused the qemu-kvm process to terminate unexpectedly, and\nthe reboot to fail. This update fixes the problem, and guests with\nhot-plugged memory reboot successfully. (BZ#1288096)\n\n* When the OHCI driver received an interrupt during the suspending\nprocess, the interrupt was not acknowledged. As a consequence, the\ninterrupt kept being sent repeatedly, and the system became\nunresponsive. This update modifies the suspend procedure to\nacknowledge the interrupt, which prevents the described problem.\n(BZ#1298971)\n\nAll qemu-kvm-rhev users are advised to upgrade to these updated\npackages, which contain backported patches to correct these issues.\nAfter installing this update, shut down all running virtual machines.\nOnce all virtual machines have shut down, start them again for this\nupdate to take effect.\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://access.redhat.com/errata/RHSA-2016:0084\"\n );\n script_set_attribute(\n
