Multiple vulnerabilities were found in qemu, a fast processor emulator :

  - CVE-2017-9375     Denial of service via memory leak in USB XHCI emulation.

  - CVE-2017-12809     Denial of service in the CDROM device drive emulation.

  - CVE-2017-13672     Denial of service in VGA display emulation.

  - CVE-2017-13711     Denial of service in SLIRP networking support.

  - CVE-2017-14167     Incorrect validation of multiboot headers could result     in the execution of arbitrary code.

An out-of-bounds read access issue was found in the VGA display emulator built into the Quick emulator (QEMU). It could occur while reading VGA memory to update graphics display. A privileged user/process inside guest could use this flaw to crash the QEMU process on the host resulting in denial of service situation.(CVE-2017-13672)

A memory leakage issue was found in the I/O channels websockets implementation of the Quick Emulator (QEMU). It could occur while sending screen updates to a client, which is slow to read and process them further. A privileged guest user could use this flaw to cause a denial of service on the host and/or potentially crash the QEMU process instance on the host.(CVE-2017-15268)

A use-after-free issue was found in the Slirp networking implementation of the Quick emulator (QEMU). It occurs when a Socket referenced from multiple packets is freed while responding to a message. A user/process could use this flaw to crash the QEMU process on the host resulting in denial of service.(CVE-2017-13711 )

Quick Emulator (aka QEMU), when built with the Cirrus CLGD 54xx VGA Emulator support, allows local guest OS privileged users to cause a denial of service (out-of-bounds access and QEMU process crash) by leveraging incorrect region calculation when updating VGA display.(CVE-2018-7858)

VNC server implementation in Quick Emulator (QEMU) was found to be vulnerable to an unbounded memory allocation issue, as it did not throttle the framebuffer updates sent to its client. If the client did not consume these updates, VNC server allocates growing memory to hold onto this data. A malicious remote VNC client could use this flaw to cause DoS to the server host.(CVE-2017-15124)

An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to read privileged memory by conducting targeted cache side-channel attacks.(CVE-2018-3639)

An out-of-bounds read access issue was found in the VGA emulator of QEMU. It could occur in vga_draw_text routine, while updating display area for a vnc client. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS.(CVE-2018-5683)

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

  - QEMU (aka Quick Emulator), when built with the VGA     display emulator support, allows local guest OS     privileged users to cause a denial of service     (out-of-bounds read and QEMU process crash) via vectors     involving display update.(CVE-2017-13672)

  - Use-after-free vulnerability in the sofree function in     slirp/socket.c in QEMU (aka Quick Emulator) allows     attackers to cause a denial of service (QEMU instance     crash) by leveraging failure to properly clear ifq_so     from pending packets.(CVE-2017-13711)

  - VNC server implementation in Quick Emulator (QEMU)     2.11.0 and older was found to be vulnerable to an     unbounded memory allocation issue, as it did not     throttle the framebuffer updates sent to its client. If     the client did not consume these updates, VNC server     allocates growing memory to hold onto this data. A     malicious remote VNC client could use this flaw to     cause DoS to the server host.(CVE-2017-15124)

  - Qemu through 2.10.0 allows remote attackers to cause a     memory leak by triggering slow data-channel read     operations, related to     io/channel-websock.c.(CVE-2017-15268)

  - The vga_draw_text function in Qemu allows local OS     guest privileged users to cause a denial of service     (out-of-bounds read and QEMU process crash) by     leveraging improper memory address     validation.(CVE-2018-5683)

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of Load i1/4+ Store instructions (a commonly     used performance optimization). It relies on the     presence of a precisely-defined instruction sequence in     the privileged code as well as the fact that memory     read from address to which a recent memory write has     occurred may see an older value and subsequently cause     an update into the microprocessor's data cache even for     speculatively executed instructions that never actually     commit (retire). As a result, an unprivileged attacker     could use this flaw to read privileged memory by     conducting targeted cache side-channel attacks.

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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

  - Quick Emulator (Qemu) built with the VirtFS, host     directory sharing via Plan 9 File System(9pfs) support,     is vulnerable to an improper access control issue. It     could occur while accessing virtfs metadata files in     mapped-file security mode. A guest user could use this     flaw to escalate their privileges inside     guest.(CVE-2017-7493)

  - qemu-bridge-helper.c in QEMU 4.0.0 does not ensure that     a network interface name (obtained from bridge.conf or     a --br=bridge option) is limited to the IFNAMSIZ size,     which can lead to an ACL bypass.(CVE-2019-13164)

  - Qemu has a Buffer Overflow in pcnet_receive in     hw/net/pcnet.c because an incorrect integer data type     is used.(CVE-2018-17962)

  - Buffer overflow in the 'megasas_mmio_write' function in     Qemu 2.9.0 allows remote attackers to have unspecified     impact via unknown vectors.(CVE-2017-8380)

  - qemu_deliver_packet_iov in net/net.c in Qemu accepts     packet sizes greater than INT_MAX, which allows     attackers to cause a denial of service or possibly have     unspecified other impact.(CVE-2018-17963)

  - In QEMU 3.1.0, load_device_tree in device_tree.c calls     the deprecated load_image function, which has a buffer     overflow risk.(CVE-2018-20815)

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

  - An issue was discovered in ide_dma_cb() in     hw/ide/core.c in QEMU 2.4.0 through 4.2.0. The guest     system can crash the QEMU process in the host system     via a special SCSI_IOCTL_SEND_COMMAND. It hits an     assertion that implies that the size of successful DMA     transfers there must be a multiple of 512 (the size of     a sector). NOTE: a member of the QEMU security team     disputes the significance of this issue because a     'privileged guest user has many ways to cause similar     DoS effect, without triggering this     assert.'(CVE-2019-20175)

  - Use-after-free vulnerability in the sofree function in     slirp/socket.c in QEMU (aka Quick Emulator) allows     attackers to cause a denial of service (QEMU instance     crash) by leveraging failure to properly clear ifq_so     from pending packets.(CVE-2017-13711)

  - Qemu has a Buffer Overflow in rtl8139_do_receive in     hw/net/rtl8139.c because an incorrect integer data type     is used.(CVE-2018-17958)

  - ip_reass in ip_input.c in libslirp 4.0.0 has a     heap-based buffer overflow via a large packet because     it mishandles a case involving the first     fragment.(CVE-2019-14378)

  - m_cat in slirp/mbuf.c in Qemu has a heap-based buffer     overflow via incoming fragmented     datagrams.(CVE-2018-11806)

  - Memory leak in the audio/audio.c in QEMU (aka Quick     Emulator) allows remote attackers to cause a denial of     service (memory consumption) by repeatedly starting and     stopping audio capture.(CVE-2017-8309)

  - Memory leak in the keyboard input event handlers     support in QEMU (aka Quick Emulator) allows local guest     OS privileged users to cause a denial of service (host     memory consumption) by rapidly generating large     keyboard events.(CVE-2017-8379)

  - hw/input/ps2.c in Qemu does not validate 'rptr' and     'count' values during guest migration, leading to     out-of-bounds access(CVE-2017-16845)

  - The cirrus_invalidate_region function in     hw/display/cirrus_vga.c in Qemu allows local OS guest     privileged users to cause a denial of service     (out-of-bounds array access and QEMU process crash) via     vectors related to negative pitch.(CVE-2017-18030)

  - An out-of-bounds read/write access flaw was found in     the USB emulator of the QEMU in versions before 5.2.0.
    This issue occurs while processing USB packets from a     guest when USBDevice 'setup_len' exceeds its     'data_buf[4096]' in the do_token_in, do_token_out     routines. This flaw allows a guest user to crash the     QEMU process, resulting in a denial of service, or the     potential execution of arbitrary code with the     privileges of the QEMU process on the     host.(CVE-2020-14364)

Additional Changes :

For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.5 Release Notes linked from the References section.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:1113 advisory.

    KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on a variety of     architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines     that use KVM in environments managed by Red Hat products.

    Security Fix(es):

    * The Network Block Device (NBD) server in Quick Emulator (QEMU), is vulnerable to a denial of service     issue. It could occur if a client sent large option requests, making the server waste CPU time on reading     up to 4GB per request. A client could use this flaw to keep the NBD server from serving other requests,     resulting in DoS. (CVE-2017-15119)

    * Qemu: vga: OOB read access during display update (CVE-2017-13672)

    * Qemu: vga: reachable assert failure during display update (CVE-2017-13673)

    * Qemu: Slirp: use-after-free when sending response (CVE-2017-13711)

    * VNC server implementation in Quick Emulator (QEMU) was found to be vulnerable to an unbounded memory     allocation issue, as it did not throttle the framebuffer updates sent to its client. If the client did not     consume these updates, VNC server allocates growing memory to hold onto this data. A malicious remote VNC     client could use this flaw to cause DoS to the server host. (CVE-2017-15124)
