Security update for kvm SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2016:2628-1 Final 1 1 2016-10-25T14:22:27Z current 2016-10-25T14:22:27Z 2016-10-25T14:22:27Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for kvm kvm was updated to fix 16 security issues. These security issues were fixed: - CVE-2015-6815: e1000 NIC emulation support was vulnerable to an infinite loop issue. A privileged user inside guest could have used this flaw to crash the Qemu instance resulting in DoS. (bsc#944697). - CVE-2016-2391: The ohci_bus_start function in the USB OHCI emulation support (hw/usb/hcd-ohci.c) in QEMU allowed local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors related to multiple eof_timers (bsc#967013). - CVE-2016-2392: The is_rndis function in the USB Net device emulator (hw/usb/dev-network.c) in QEMU did not properly validate USB configuration descriptor objects, which allowed local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors involving a remote NDIS control message packet (bsc#967012). - CVE-2016-4453: The vmsvga_fifo_run function in hw/display/vmware_vga.c in QEMU allowed local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via a VGA command (bsc#982223). - CVE-2016-4454: The vmsvga_fifo_read_raw function in hw/display/vmware_vga.c in QEMU allowed local guest OS administrators to obtain sensitive host memory information or cause a denial of service (QEMU process crash) by changing FIFO registers and issuing a VGA command, which triggers an out-of-bounds read (bsc#982222). - CVE-2016-5105: The megasas_dcmd_cfg_read function in hw/scsi/megasas.c in QEMU, when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, used an uninitialized variable, which allowed local guest administrators to read host memory via vectors involving a MegaRAID Firmware Interface (MFI) command (bsc#982017). - CVE-2016-5106: The megasas_dcmd_set_properties function in hw/scsi/megasas.c in QEMU, when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, allowed local guest administrators to cause a denial of service (out-of-bounds write access) via vectors involving a MegaRAID Firmware Interface (MFI) command (bsc#982018). - CVE-2016-5107: The megasas_lookup_frame function in QEMU, when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, allowed local guest OS administrators to cause a denial of service (out-of-bounds read and crash) via unspecified vectors (bsc#982019). - CVE-2016-5126: Heap-based buffer overflow in the iscsi_aio_ioctl function in block/iscsi.c in QEMU allowed local guest OS users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code via a crafted iSCSI asynchronous I/O ioctl call (bsc#982285). - CVE-2016-5238: The get_cmd function in hw/scsi/esp.c in QEMU allowed local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via vectors related to reading from the information transfer buffer in non-DMA mode (bsc#982959). - CVE-2016-5337: The megasas_ctrl_get_info function in hw/scsi/megasas.c in QEMU allowed local guest OS administrators to obtain sensitive host memory information via vectors related to reading device control information (bsc#983961). - CVE-2016-5338: The (1) esp_reg_read and (2) esp_reg_write functions in hw/scsi/esp.c in QEMU allowed local guest OS administrators to cause a denial of service (QEMU process crash) or execute arbitrary code on the QEMU host via vectors related to the information transfer buffer (bsc#983982). - CVE-2016-5403: The virtqueue_pop function in hw/virtio/virtio.c in QEMU allowed local guest OS administrators to cause a denial of service (memory consumption and QEMU process crash) by submitting requests without waiting for completion (bsc#991080). - CVE-2016-6490: Infinite loop in the virtio framework. A privileged user inside the guest could have used this flaw to crash the Qemu instance on the host resulting in DoS (bsc#991466). - CVE-2016-7116: Host directory sharing via Plan 9 File System(9pfs) was vulnerable to a directory/path traversal issue. A privileged user inside guest could have used this flaw to access undue files on the host (bsc#996441). - CVE-2014-7815: The set_pixel_format function in ui/vnc.c in QEMU allowed remote attackers to cause a denial of service (crash) via a small bytes_per_pixel value (bsc#902737).
