update for qemu","description":"This update for qemu to version 2.6.2 fixes the several issues.\n\nThese security issues were fixed:\n- 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).\n- CVE-2016-7170: OOB stack memory access when processing svga command (bsc#998516).\n- CVE-2016-7466: xhci memory leakage during device unplug (bsc#1000345).\n- CVE-2016-7422: NULL pointer dereference in virtqueu_map_desc (bsc#1000346).\n- 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).\n- CVE-2016-7995: Memory leak in ehci_process_itd (bsc#1003612).\n- 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).\n- 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).\n- CVE-2016-9105: Memory leakage in v9fs_link (bsc#1007494).\n- 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).\n- CVE-2016-9106: Memory leakage in v9fs_write (bsc#1007495).\n- 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).\n- 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).\n- CVE-2016-9101: eepro100 memory leakage whern unplugging a device (bsc#1007391).\n- 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).\n- 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).\n- 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).\n- CVE-2016-7994: Memory leak in virtio_gpu_resource_create_2d (bsc#1003613).\n- CVE-2016-9104: Integer overflow leading to OOB access in 9pfs (bsc#1007493).\n- 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).\n- 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).\n\nThese non-security issues were fixed:\n- Change kvm-supported.txt to be per-architecture documentation, stored in the\n  package documentation directory of each per-arch package (bsc#1005353).\n- Update support doc to include current ARM64 (AArch64) support stance (bsc#1005374).\n- Fix migration failure when snapshot also has been done (bsc#1008148).\n- Change package post script udevadm trigger calls to be device specific (bsc#1002116).\n- Add qmp-commands.txt documentation file back in. It was inadvertently dropped.\n- Add an x86 cpu option (l3-cache) to specify that an L3 cache is present and\n  another option (cpuid-0xb) to enable the cpuid 0xb leaf (bsc#1007769).\n\nFor Leap 42.2 this update also enabled the smartcard support (bsc#1007263).\n","status":"published","published":"2016-11-22T14:26:40Z","modified":"2026-02-04T04:14:51.939445Z","updated_at":"2026-11-02T15:53:43.438985Z"},{"id":"SUSE-SU-2016:2902-1","title":"Security update for kvm","description":"\nThis update for kvm fixes the following issues:\n\n- Address various security/stability issues\n * Fix OOB access in xlnx.xpx-ethernetlite emulation (CVE-2016-7161 bsc#1001151)\n * Fix OOB access in VMware SVGA emulation (CVE-2016-7170 bsc#998516)\n * Fix DOS in ColdFire Fast Ethernet Controller emulation\n   (CVE-2016-7908 bsc#1002550)\n * Fix DOS in USB xHCI emulation (CVE-2016-8576 bsc#1003878)\n * Fix DOS in virtio-9pfs (CVE-2016-8578 bsc#1003894)\n * Fix DOS in virtio-9pfs (CVE-2016-9105 bsc#1007494)\n * Fix DOS in virtio-9pfs (CVE-2016-8577 bsc#1003893)\n * Plug data leak in virtio-9pfs interface (CVE-2016-9103 bsc#1007454)\n * Fix DOS in virtio-9pfs interface (CVE-2016-9102 bsc#1007450)\n * Fix DOS in virtio-9pfs (CVE-2016-9106 bsc#1007495)\n * Fix DOS in 16550A UART emulation (CVE-2016-8669 bsc#1004707)\n * Fix DOS in PC-Net II emulation (CVE-2016-7909 bsc#1002557)\n * Fix DOS in PRO100 emulation (CVE-2016-9101 bsc#1007391)\n * Fix DOS in RTL8139 emulation (CVE-2016-8910 bsc#1006538)\n * Fix DOS in Intel HDA controller emulation (CVE-2016-8909 bsc#1006536)\n * Fix DOS in virtio-9pfs (CVE-2016-9104 bsc#1007493)\n * Fix DOS in JAZZ RC4030 emulation (CVE-2016-8667 bsc#1004702)\n\n- Patch queue updated from https://gitlab.suse.de/virtualization/qemu.git SLE11-SP4\n- Remove semi-contradictory and now determined erroneous statement\n  in kvm-supported.txt regarding not running ntp in kvm guest when\n  kvm-clock is used.
