SUSE-SU-2016:2879-1

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-2016-7422: NULL pointer dereference in virtqueu_map_desc (bsc#1000346).
• 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).

These non-security issues were fixed:

• Change kvm-supported.txt to be per-architecture documentation, stored in the package documentation directory of each per-arch package (bsc#1005353).
• Update support doc to include current ARM64 (AArch64) support stance (bsc#1005374).
• Fix migration failure when snapshot also has been done (bsc#1008148).
• Change package post script udevadm trigger calls to be device specific (bsc#1002116).
• Add qmp-commands.txt documentation file back in. It was inadvertently dropped.
• Add an x86 cpu option (l3-cache) to specify that an L3 cache is present and another option (cpuid-0xb) to enable the cpuid 0xb leaf (bsc#1007769).

For Leap 42.2 this update also enabled the smartcard support (bsc#1007263).
