SUSE SLES12 Security Update : qemu (SUSE-SU-2016:2781-1)

Medium Nessus Plugin ID 94758

Synopsis

The remote SUSE host is missing one or more security updates.

Description

qemu was updated to fix 21 security issues. These security issues were fixed :

- CVE-2014-5388: Off-by-one error in the pci_read function in the ACPI PCI hotplug interface (hw/acpi/pcihp.c) in QEMU allowed local guest users to obtain sensitive information and have other unspecified impact related to a crafted PCI device that triggers memory corruption (bsc#893323).

- 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-2016-6833: Use-after-free issue in the VMWARE VMXNET3 NIC device support. A privileged user inside guest could have used this issue to crash the Qemu instance resulting in DoS (bsc#994774).

- CVE-2016-6836: VMWARE VMXNET3 NIC device support was leaging information leakage. A privileged user inside guest could have used this to leak host memory bytes to a guest (bsc#994760).

- CVE-2016-6888: Integer overflow in packet initialisation in VMXNET3 device driver. A privileged user inside guest could have used this flaw to crash the Qemu instance resulting in DoS (bsc#994771).

- 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-2016-7155: In the VMWARE PVSCSI paravirtual SCSI bus a OOB access and/or infinite loop issue could have allowed a privileged user inside guest to crash the Qemu process resulting in DoS (bsc#997858).

- CVE-2016-7156: In the VMWARE PVSCSI paravirtual SCSI bus a infinite loop issue could have allowed a privileged user inside guest to crash the Qemu process resulting in DoS (bsc#997859).
