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

  - The imx_fec_do_tx function in hw/net/imx_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-2016-7907)

  - Stack-based buffer overflow in hw/usb/redirect.c in     QEMU (aka Quick Emulator) allows local guest OS users     to cause a denial of service (QEMU process crash) via     vectors related to logging debug     messages.(CVE-2017-10806)

  - The dhcp_decode function in slirp/bootp.c in QEMU (aka     Quick Emulator) allows local guest OS users to cause a     denial of service (out-of-bounds read and QEMU process     crash) via a crafted DHCP options     string.(CVE-2017-11434)

  - 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)

  - 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)

  - A heap buffer overflow issue was found in the way SLiRP     networking back-end in QEMU processes fragmented     packets. It could occur while reassembling the     fragmented datagrams of an incoming packet. A     privileged user/process inside guest could use this     flaw to crash the QEMU process resulting in DoS or     potentially leverage it to execute arbitrary code on     the host with privileges of the QEMU     process.(CVE-2018-11806)

  - qemu-seccomp.c in QEMU might allow local OS guest users     to cause a denial of service (guest crash) by     leveraging mishandling of the seccomp policy for     threads other than the main thread.(CVE-2018-15746)

  - An integer overflow issue was found in the RTL8139 NIC     emulation in QEMU. It could occur while receiving     packets over the network if the size value is greater     than INT_MAX. Such overflow would lead to stack buffer     overflow issue. A user inside guest could use this flaw     to crash the QEMU process, resulting in DoS     scenario.(CVE-2018-17958)

  - An integer overflow issue was found in the AMD PC-Net     II NIC emulation in QEMU. It could occur while     receiving packets, if the size value was greater than     INT_MAX. Such overflow would lead to stack buffer     overflow issue. A user inside guest could use this flaw     to crash the QEMU process resulting in     DoS.(CVE-2018-17962)

  - A heap buffer overflow issue was found in the     load_device_tree() function of QEMU, which is invoked     to load a device tree blob at boot time. It occurs due     to device tree size manipulation before buffer     allocation, which could overflow a signed int type. A     user/process could use this flaw to potentially execute     arbitrary code on a host system with privileges of the     QEMU process.(CVE-2018-20815)

  - interface_release_resource in hw/display/qxl.c in QEMU     3.1.x through 4.0.0 has a NULL pointer     dereference.(CVE-2019-12155)

  - qemu-bridge-helper.c in QEMU 3.1 and 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)

  - A heap buffer overflow issue was found in the SLiRP     networking implementation of the QEMU emulator. This     flaw occurs in the ip_reass() routine while     reassembling incoming packets if the first fragment is     bigger than the m->m_dat[] buffer. An attacker could     use this flaw to crash the QEMU process on the host,     resulting in a Denial of Service or potentially     executing arbitrary code with privileges of the QEMU     process.(CVE-2019-14378)

  - 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)

  - An out-of-bounds read vulnerability was found in the     SLiRP networking implementation of the QEMU emulator.
    This flaw occurs in the icmp6_send_echoreply() routine     while replying to an ICMP echo request, also known as     ping. This flaw allows a malicious guest to leak the     contents of the host memory, resulting in possible     information disclosure.(CVE-2020-10756)

  - A heap buffer overflow issue was found in the SLiRP     networking implementation of the QEMU emulator. This     flaw occurs in the tcp_emu() routine while emulating     IRC and other protocols. An attacker could use this     flaw to crash the QEMU process on the host, resulting     in a denial of service or potential execution of     arbitrary code with privileges of the QEMU     process.(CVE-2020-7039)

  - An out-of-bound write access flaw was found in the way     QEMU loads ROM contents at boot time. This flaw occurs     in the rom_copy() routine while loading the contents of     a 32-bit -kernel image into memory. Running an     untrusted -kernel image may load contents at arbitrary     memory locations, potentially leading to code execution     with the privileges of the QEMU     process.(CVE-2020-13765)

  - A use-after-free flaw was found in the USB(xHCI/eHCI)     controller emulators of QEMU. This flaw occurs while     setting up the USB packet as a usb_packet_map() routine     and returns an error that was not checked. This flaw     allows a guest user or process to crash the QEMU     process, resulting in a denial of     service.(CVE-2020-25084)

  - An infinite loop flaw was found in the USB OHCI     controller emulator of QEMU. This flaw occurs while     servicing OHCI isochronous transfer descriptors (TD) in     the ohci_service_iso_td routine, as it retires a TD if     it has passed its time frame. It does not check if the     TD was already processed and holds an error code in     TD_CC. This issue may happen if the TD list has a loop.
    This flaw allows a guest user or process to consume CPU     cycles on the host, resulting in a denial of     service.(CVE-2020-25625)

  - A reachable assertion issue was found in the USB EHCI     emulation code of QEMU. It could occur while processing     USB requests due to missing handling of DMA memory map     failure. A malicious privileged user within the guest     may abuse this flaw to send bogus USB requests and     crash the QEMU process on the host, resulting in a     denial of service.(CVE-2020-25723)

  - A potential directory traversal issue was found in the     tftp server of the SLiRP user-mode networking     implementation used by QEMU. It could occur on a     Windows host, as it allows the use of both forward     ('/') and backward slash('\') tokens as separators in a     file path. A user able to access the tftp server could     use this flaw to access undue files by using relative     paths.(CVE-2020-7211)

  - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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)

  - 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)
