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'.

  - 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).

These non-security issues were fixed :

  - Fixed uint64 property parsing and add regression tests     (bsc#937125)

    Li Qiang discovered that QEMU incorrectly handled Plan 9 File System (9pfs) support. A privileged attacker     inside the guest could use this issue to cause QEMU to consume resources, resulting in a denial of     service. (CVE-2016-9102, CVE-2016-9104, CVE-2016-9105)

    Li Qiang discovered that QEMU incorrectly handled Plan 9 File System (9pfs) support. A privileged attacker     inside the guest could use this issue to possibly to obtain sensitive host memory. (CVE-2016-9103)

    Li Qiang discovered that QEMU incorrectly handled Plan 9 File System (9pfs) support. A privileged attacker     inside the guest could use this issue to cause QEMU to consume resources, resulting in a denial of     service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-9106)

Several vulnerabilities were discovered in qemu, a fast processor emulator. The Common Vulnerabilities and Exposures project identifies the following problems :

CVE-2016-7909

Quick Emulator(Qemu) built with the AMD PC-Net II emulator support is vulnerable to an infinite loop issue. It could occur while receiving packets via pcnet_receive().

A privileged user/process inside guest could use this issue to crash the Qemu process on the host leading to DoS.

CVE-2016-8909

Quick Emulator(Qemu) built with the Intel HDA controller emulation support is vulnerable to an infinite loop issue. It could occur while processing the DMA buffer stream while doing data transfer in 'intel_hda_xfer'.

A privileged user inside guest could use this flaw to consume excessive CPU cycles on the host, resulting in DoS.

CVE-2016-8910

Quick Emulator(Qemu) built with the RTL8139 ethernet controller emulation support is vulnerable to an infinite loop issue. It could occur while transmitting packets in C+ mode of operation.

A privileged user inside guest could use this flaw to consume excessive CPU cycles on the host, resulting in DoS situation.

CVE-2016-9101

Quick Emulator(Qemu) built with the i8255x (PRO100) NIC emulation support is vulnerable to a memory leakage issue. It could occur while unplugging the device, and doing so repeatedly would result in leaking host memory affecting, other services on the host.

A privileged user inside guest could use this flaw to cause a DoS on the host and/or potentially crash the Qemu process on the host.

CVE-2016-9102 CVE-2016-9105 CVE-2016-9106

Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9 File System(9pfs) support, is vulnerable to a several memory leakage issues.

A privileged user inside guest could use this flaws to leak the host memory bytes resulting in DoS for other services.

CVE-2016-9104

Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9 File System(9pfs) support, is vulnerable to an integer overflow issue. It could occur by accessing xattributes values.

A privileged user inside guest could use this flaw to crash the Qemu process instance resulting in DoS.

CVE-2016-9103

Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9 File System(9pfs) support, is vulnerable to an information leakage issue. It could occur by accessing xattribute value before it's written to.

A privileged user inside guest could use this flaw to leak host memory bytes.

For Debian 7 'Wheezy', these problems have been fixed in version 1.1.2+dfsg-6+deb7u18.

We recommend that you upgrade your qemu packages.
