This update for qemu to version 2.6.2 fixes the several issues. These security issues were fixed :

  - CVE-2016-7161: Heap-based buffer overflow in the     .receive callback of xlnx.xps-ethernetlite in QEMU (aka     Quick Emulator) allowed attackers to execute arbitrary     code on the QEMU host via a large ethlite packet     (bsc#1001151).

  - CVE-2016-7170: OOB stack memory access when processing     svga command (bsc#998516).

  - CVE-2016-7466: xhci memory leakage during device unplug     (bsc#1000345).

  - CVE-2016-7908: The mcf_fec_do_tx function in     hw/net/mcf_fec.c did not properly limit the buffer     descriptor count when transmitting packets, which     allowed local guest OS administrators to cause a denial     of service (infinite loop and QEMU process crash) via     vectors involving a buffer descriptor with a length of 0     and crafted values in bd.flags (bsc#1002550).

  - CVE-2016-7995: Memory leak in ehci_process_itd     (bsc#1003612).

  - CVE-2016-8576: The xhci_ring_fetch function in     hw/usb/hcd-xhci.c allowed local guest OS administrators     to cause a denial of service (infinite loop and QEMU     process crash) by leveraging failure to limit the number     of link Transfer Request Blocks (TRB) to process     (bsc#1003878).

  - CVE-2016-8578: The v9fs_iov_vunmarshal function in     fsdev/9p-iov-marshal.c allowed local guest OS     administrators to cause a denial of service (NULL     pointer dereference and QEMU process crash) by sending     an empty string parameter to a 9P operation     (bsc#1003894).

  - CVE-2016-9105: Memory leakage in v9fs_link     (bsc#1007494).

  - CVE-2016-8577: Memory leak in the v9fs_read function in     hw/9pfs/9p.c allowed local guest OS administrators to     cause a denial of service (memory consumption) via     vectors related to an I/O read operation (bsc#1003893).

  - CVE-2016-9106: Memory leakage in v9fs_write     (bsc#1007495).

  - CVE-2016-8669: The serial_update_parameters function in     hw/char/serial.c allowed local guest OS administrators     to cause a denial of service (divide-by-zero error and     QEMU process crash) via vectors involving a value of     divider greater than baud base (bsc#1004707).

  - CVE-2016-7909: The pcnet_rdra_addr function in     hw/net/pcnet.c allowed local guest OS administrators to     cause a denial of service (infinite loop and QEMU     process crash) by setting the (1) receive or (2)     transmit descriptor ring length to 0 (bsc#1002557).

  - CVE-2016-9101: eepro100 memory leakage whern unplugging     a device (bsc#1007391).

  - CVE-2016-8668: The rocker_io_writel function in     hw/net/rocker/rocker.c allowed local guest OS     administrators to cause a denial of service     (out-of-bounds read and QEMU process crash) by     leveraging failure to limit DMA buffer size     (bsc#1004706).

  - CVE-2016-8910: The rtl8139_cplus_transmit function in     hw/net/rtl8139.c allowed local guest OS administrators     to cause a denial of service (infinite loop and CPU     consumption) by leveraging failure to limit the ring     descriptor count (bsc#1006538).

  - CVE-2016-8909: The intel_hda_xfer function in     hw/audio/intel-hda.c allowed local guest OS     administrators to cause a denial of service (infinite     loop and CPU consumption) via an entry with the same     value for buffer length and pointer position     (bsc#1006536).

  - CVE-2016-7994: Memory leak in     virtio_gpu_resource_create_2d (bsc#1003613).

  - CVE-2016-9104: Integer overflow leading to OOB access in     9pfs (bsc#1007493).

  - CVE-2016-8667: The rc4030_write function in     hw/dma/rc4030.c allowed local guest OS administrators to     cause a denial of service (divide-by-zero error and QEMU     process crash) via a large interval timer reload value     (bsc#1004702).

  - CVE-2016-7907: The pcnet_rdra_addr function in     hw/net/pcnet.c allowed local guest OS administrators to     cause a denial of service (infinite loop and QEMU     process crash) by setting the (1) receive or (2)     transmit descriptor ring length to 0 (bsc#1002549).

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Memory leak in hw/net/eepro100.c in QEMU (aka Quick Emulator) allows local guest OS administrators to     cause a denial of service (memory consumption and QEMU process crash) by repeatedly unplugging an i8255x     (PRO100) NIC device. (CVE-2016-9101)

Note that Nessus relies on the presence of the package as reported by the vendor.
