EulerOS 2.0 SP5 : qemu-kvm (EulerOS-SA-2019-2227)

critical Nessus Plugin ID 130689

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the qemu-kvm packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - In QEMU 3.0.0, tcp_emu in slirp/tcp_subr.c has a heap-based buffer overflow.(CVE-2019-6778)

 - The MSI-X MMIO support in hw/pci/msix.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (NULL pointer dereference and QEMU process crash) by leveraging failure to define the .write method.(CVE-2015-7549)

 - The ne2000_receive function in the NE2000 NIC emulation support (hw/net/ne2000.c) in QEMU before 2.5.1 allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via crafted values for the PSTART and PSTOP registers, involving ring buffer control.(CVE-2016-2841)

 - Memory leak in QEMU (aka Quick Emulator), when built with USB EHCI Emulation support, allows local guest OS privileged users to cause a denial of service (memory consumption) by repeatedly hot-unplugging the device.(CVE-2017-9374)

 - Integer overflow in the macro ROUND_UP (n, d) in Quick Emulator (Qemu) allows a user to cause a denial of service (Qemu process crash).(CVE-2017-18043)

 - Memory leak in the serial_exit_core function in hw/char/serial.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (host memory consumption and QEMU process crash) via a large number of device unplug operations.(CVE-2017-5579)

 - The slirp_smb function in net/slirp.c in QEMU 2.3.0 and earlier creates temporary files with predictable names, which allows local users to cause a denial of service (instantiation failure) by creating /tmp/qemu-smb.*-* files before the program.(CVE-2015-4037)

 - The mcf_fec_do_tx function in hw/net/mcf_fec.c in QEMU (aka Quick Emulator) does not properly limit the buffer descriptor count when transmitting packets, which allows 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.(CVE-2016-7908)

 - hw/net/vmxnet3.c in QEMU 2.0.0-rc0, 1.7.1, and earlier allows local guest users to cause a denial of service or possibly execute arbitrary code via vectors related to (1) RX or (2) TX queue numbers or (3) interrupt indices. NOTE: some of these details are obtained from third party information.(CVE-2013-4544)

 - Multiple integer overflows in the USB Net device emulator (hw/usb/dev-network.c) in QEMU before 2.5.1 allow local guest OS administrators to cause a denial of service (QEMU process crash) or obtain sensitive host memory information via a remote NDIS control message packet that is mishandled in the (1) rndis_query_response, (2) rndis_set_response, or (3) usb_net_handle_dataout function.(CVE-2016-2538)

 - Qemu emulator <= 3.0.0 built with the NE2000 NIC emulation support is vulnerable to an integer overflow, which could lead to buffer overflow issue. It could occur when receiving packets over the network. A user inside guest could use this flaw to crash the Qemu process resulting in DoS.(CVE-2018-10839)

 - Memory leak in QEMU (aka Quick Emulator), when built with IDE AHCI Emulation support, allows local guest OS privileged users to cause a denial of service (memory consumption) by repeatedly hot-unplugging the AHCI device.(CVE-2017-9373)

 - tcp_emu in slirp/tcp_subr.c (aka slirp/src/tcp_subr.c) in QEMU 3.0.0 uses uninitialized data in an snprintf call, leading to Information disclosure.(CVE-2019-9824)

 - QEMU (aka Quick Emulator), when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, allows local guest OS privileged users to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors involving megasas command processing.(CVE-2017-9503)

 - Buffer overflow in hw/ide/ahci.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via vectors related to migrating ports.(CVE-2013-4526)

 - Buffer overflow in hw/ssi/pl022.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service or possibly execute arbitrary code via crafted tx_fifo_head and rx_fifo_head values in a savevm image.(CVE-2013-4530)

 - Multiple buffer overflows in the tsc210x_load function in hw/input/tsc210x.c in QEMU before 1.7.2 might allow remote attackers to execute arbitrary code via a crafted (1) precision, (2) nextprecision, (3) function, or (4) nextfunction value in a savevm image.(CVE-2013-4539)

 - Buffer overflow in scoop_gpio_handler_update in QEMU before 1.7.2 might allow remote attackers to execute arbitrary code via a large (1) prev_level, (2) gpio_level, or (3) gpio_dir value in a savevm image.(CVE-2013-4540)

 - The sdhci_sdma_transfer_multi_blocks function in hw/sd/sdhci.c in QEMU (aka Quick Emulator) allows local OS guest privileged users to cause a denial of service (infinite loop and QEMU process crash) via vectors involving the transfer mode register during multi block transfer.(CVE-2017-5987)

 - interface_release_resource in hw/display/qxl.c in QEMU 4.0.0 has a NULL pointer dereference.(CVE-2019-12155)

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

 - Heap-based buffer overflow in the ne2000_receive function in hw/net/ne2000.c in QEMU before 2.4.0.1 allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via vectors related to receiving packets.(CVE-2015-5279)

 - The sdhci_sdma_transfer_multi_blocks function in hw/sd/sdhci.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (out-of-bounds heap access and crash) or execute arbitrary code on the QEMU host via vectors involving the data transfer length.(CVE-2017-5667)
