ID CVE-2016-9921
Summary Quick emulator (Qemu) built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to a divide by zero issue. It could occur while copying VGA data when cirrus graphics mode was set to be VGA. A privileged user inside guest could use this flaw to crash the Qemu process instance on the host, resulting in DoS.

    description qemu was updated to fix several issues. These security issues were fixed : - CVE-2016-9102: Memory leak in the v9fs_xattrcreate function in hw/9pfs/9p.c in allowed local guest OS administrators to cause a denial of service (memory consumption and QEMU process crash) via a large number of Txattrcreate messages with the same fid number (bsc#1014256). - CVE-2016-9103: The v9fs_xattrcreate function in hw/9pfs/9p.c in allowed local guest OS administrators to obtain sensitive host heap memory information by reading xattribute values writing to them (bsc#1007454). - CVE-2016-9381: Improper processing of shared rings allowing guest administrators take over the qemu process, elevating their privilege to that of the qemu process (bsc#1009109) - CVE-2016-9776: The ColdFire Fast Ethernet Controller emulator support was vulnerable to an infinite loop issue while receiving packets in 'mcf_fec_receive'. A privileged user/process inside guest could have used this issue to crash the Qemu process on the host leading to DoS (bsc#1013285). - CVE-2016-9845: The Virtio GPU Device emulator support as vulnerable to an information leakage issue while processing the 'VIRTIO_GPU_CMD_GET_CAPSET_INFO' command. A guest user/process could have used this flaw to leak contents of the host memory (bsc#1013767). - CVE-2016-9846: The Virtio GPU Device emulator support was vulnerable to a memory leakage issue while updating the cursor data in update_cursor_data_virgl. A guest user/process could have used this flaw to leak host memory bytes, resulting in DoS for the host (bsc#1013764). - CVE-2016-9907: The USB redirector usb-guest support was vulnerable to a memory leakage flaw when destroying the USB redirector in 'usbredir_handle_destroy'. A guest user/process could have used this issue to leak host memory, resulting in DoS for a host (bsc#1014109). - CVE-2016-9908: The Virtio GPU Device emulator support was vulnerable to an information leakage issue while processing the 'VIRTIO_GPU_CMD_GET_CAPSET' command. A guest user/process could have used this flaw to leak contents of the host memory (bsc#1014514). - CVE-2016-9911: The USB EHCI Emulation support was vulnerable to a memory leakage issue while processing packet data in 'ehci_init_transfer'. A guest user/process could have used this issue to leak host memory, resulting in DoS for the host (bsc#1014111). - CVE-2016-9912: The Virtio GPU Device emulator support was vulnerable to a memory leakage issue while destroying gpu resource object in 'virtio_gpu_resource_destroy'. A guest user/process could have used this flaw to leak host memory bytes, resulting in DoS for the host (bsc#1014112). - CVE-2016-9913: VirtFS was vulnerable to memory leakage issue via its '9p-handle' or '9p-proxy' backend drivers. A privileged user inside guest could have used this flaw to leak host memory, thus affecting other services on the host and/or potentially crash the Qemu process on the host (bsc#1014110). The update package also includes non-security fixes. See advisory for details.

    NASL id DEBIAN_DLA-765.NASL
    description Multiple vulnerabilities have been found in qemu-kvm : CVE-2016-9911 qemu-kvm built with the USB EHCI Emulation support is vulnerable to a memory leakage issue. It could occur while processing packet data in 'ehci_init_transfer'. A guest user/process could use this issue to leak host memory, resulting in DoS for a host. CVE-2016-9921, CVE-2016-9922 qemu-kvm built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to a divide by zero issue. It could occur while copying VGA data when cirrus graphics mode was set to be VGA. A privileged user inside guest could use this flaw to crash the Qemu process instance on the host, resulting in DoS. For Debian 7 'Wheezy', these problems have been fixed in version 1.1.2+dfsg-6+deb7u19. We recommend that you upgrade your qemu-kvm packages. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    title openSUSE Security Update : xen (openSUSE-2017-329)
  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2017-2392.NASL
    description An update for qemu-kvm-rhev is now available for RHEV 4.X RHEV-H and Agents for RHEL 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines that use KVM in environments managed by Red Hat products. The following packages have been upgraded to a later upstream version: qemu-kvm-rhev (2.9.0). (BZ#1387372, BZ#1387600, BZ#1400962) Security Fix(es) : * A stack-based buffer overflow flaw was found in the Quick Emulator (QEMU) built with the Network Block Device (NBD) client support. The flaw could occur while processing server's response to a 'NBD_OPT_LIST' request. A malicious NBD server could use this issue to crash a remote NBD client resulting in DoS or potentially execute arbitrary code on client host with privileges of the QEMU process. (CVE-2017-2630) * An integer overflow flaw was found in Quick Emulator (QEMU) in the CCID Card device support. The flaw could occur while passing messages via command/response packets to and from the host. A privileged user inside a guest could use this flaw to crash the QEMU process. (CVE-2017-5898) * An information exposure flaw was found in Quick Emulator (QEMU) in Task Priority Register (TPR) optimizations for 32-bit Windows guests. The flaw could occur while accessing TPR. A privileged user inside a guest could use this issue to read portions of the host memory. (CVE-2016-4020) * A memory-leak flaw was found in the Quick Emulator(QEMU) built with USB xHCI controller emulation support. The flaw could occur while doing a USB-device unplug operation. Unplugging the device repeatedly resulted in leaking host memory, affecting other services on the host. A privileged user inside the guest could exploit this flaw to cause a denial of service on the host or potentially crash the host's QEMU process instance. (CVE-2016-7466) * Multiple CVEs(CVE-2016-10155, CVE-2016-4020, CVE-2016-6835, CVE-2016-6888, CVE-2016-7422, CVE-2016-7466, CVE-2016-8576, CVE-2016-8669, CVE-2016-8909, CVE-2016-8910, CVE-2016-9907, CVE-2016-9911, CVE-2016-9921, CVE-2016-9922, CVE-2017-2630, CVE-2017-5579, CVE-2017-5898, CVE-2017-5973, CVE-2017-9310, CVE-2017-9373, CVE-2017-9374, CVE-2017-9375) were fixed as result of rebase to QEMU version 2.9.0. Red Hat would like to thank Li Qiang (Qihoo 360 Inc.) for reporting CVE-2016-6835 and CVE-2016-6888; Li Qiang (360.cn Inc.) for reporting CVE-2017-5898, CVE-2016-7466, CVE-2016-10155, CVE-2017-5579, and CVE-2017-5973; Donghai Zdh (Alibaba Inc.) for reporting CVE-2016-4020; Qinghao Tang (Marvel Team 360.cn Inc.) and Zhenhao Hong (Marvel Team 360.cn Inc.) for reporting CVE-2016-7422; PSIRT (Huawei Inc.) for reporting CVE-2016-8669; Andrew Henderson (Intelligent Automation Inc.) for reporting CVE-2016-8910; Qinghao Tang (Qihoo 360), Li Qiang (Qihoo 360), and Jiangxin (Huawei Inc.) for reporting CVE-2016-9921 and CVE-2016-9922; and Li Qiang (Qihoo 360 Gear Team) for reporting CVE-2017-9310, CVE-2017-9373, CVE-2017-9374, and CVE-2017-9375. Additional Changes : This update also fixes several bugs and adds various enhancements. Documentation for these changes is available from the Release Notes document linked to in the References section.
