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

    QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed.QEMU has two     operating modes: Full system emulation. In this mode, QEMU emulates a full system (for example a PC),     including one or several processors and various peripherals. It can be used to launch different Operating     Systems without rebooting the PC or to debug system code. User mode emulation. In this mode, QEMU can     launch processes compiled for one CPU on another CPU. It can be used to launch the Wine Windows API     emulator (https://www.winehq.org) or to ease cross-compilation and cross-debugging.You can refer to     https://www.qemu.org for more infortmation.A heap based buffer overflow was found in the SDHCI device     emulation of QEMU. The bug is triggered when both `s-data_count` and the size of `s-fifo_buffer` are     set to 0x200, leading to an out-of-bound access. A malicious guest could use this flaw to crash the QEMU     process on the host, resulting in a denial of service condition.(CVE-2024-3447     )

This issue could allow a malicious privileged guest user to crash     the QEMU process on the host, resulting in a denial of service or allow arbitrary code execution within     the context of the QEMU process on the host.(CVE-2024-3446)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization qemu security advisory.

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

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:1394-1 advisory.

  - A DMA reentrancy issue leading to a use-after-free error was found in the e1000e NIC emulation code in     QEMU. This issue could allow a privileged guest user to crash the QEMU process on the host, resulting in a     denial of service. (CVE-2023-3019)

  - A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. The     qemu_clipboard_request() function can be reached before vnc_server_cut_text_caps() was called and had the     chance to initialize the clipboard peer, leading to a NULL pointer dereference. This could allow a     malicious authenticated VNC client to crash QEMU and trigger a denial of service. (CVE-2023-6683)

  - QEMU before 8.2.0 has an integer underflow, and resultant buffer overflow, via a TI command when an     expected non-DMA transfer length is less than the length of the available FIFO data. This occurs in     esp_do_nodma in hw/scsi/esp.c because of an underflow of async_len. (CVE-2024-24474)

  - A double free vulnerability was found in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio-     crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. This     issue could allow a malicious privileged guest user to crash the QEMU process on the host, resulting in a     denial of service or allow arbitrary code execution within the context of the QEMU process on the host.

The remote NewStart CGSL host, running version MAIN 7.02, has qemu packages installed that are affected by multiple vulnerabilities:

  - A stack based buffer overflow was found in the virtio-net device of QEMU. This issue occurs when flushing     TX in the virtio_net_flush_tx function if guest features VIRTIO_NET_F_HASH_REPORT, VIRTIO_F_VERSION_1 and     VIRTIO_NET_F_MRG_RXBUF are enabled. This could allow a malicious user to overwrite local variables     allocated on the stack. Specifically, the `out_sg` variable could be used to read a part of process memory     and send it to the wire, causing an information leak. (CVE-2023-6693)

  - A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. A wrong exit     condition may lead to an infinite loop when inflating an attacker controlled zlib buffer in the     `inflate_buffer` function. This could allow a remote authenticated client who is able to send a clipboard     to the VNC server to trigger a denial of service. (CVE-2023-3255)

  - A flaw was found in QEMU. The async nature of hot-unplug enables a race scenario where the net device     backend is cleared before the virtio-net pci frontend has been unplugged. A malicious guest could use this     time window to trigger an assertion and cause a denial of service. (CVE-2023-3301)

  - A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. The     qemu_clipboard_request() function can be reached before vnc_server_cut_text_caps() was called and had the     chance to initialize the clipboard peer, leading to a NULL pointer dereference. This could allow a     malicious authenticated VNC client to crash QEMU and trigger a denial of service. (CVE-2023-6683)

  - A double free vulnerability was found in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio-     crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. This     issue could allow a malicious privileged guest user to crash the QEMU process on the host, resulting in a     denial of service or allow arbitrary code execution within the context of the QEMU process on the host.
    (CVE-2024-3446)

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:9136 advisory.

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

    Security Fix(es):

    * QEMU: SR-IOV: improper validation of NumVFs leads to buffer overflow (CVE-2024-26327)

    * QEMU: virtio: DMA reentrancy issue leads to double free vulnerability (CVE-2024-3446)

    * QEMU: Denial of Service via Improper Synchronization in QEMU NBD Server During Socket Closure     (CVE-2024-7409)

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7744-1 advisory.

    It was discovered that QEMU incorrectly handled certain virtio devices. A privileged guest attacker could     use this issue to cause QEMU to crash, leading to a denial of service, or possibly execute arbitrary code.
    This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-3446)

    It was discovered that QEMU incorrectly handled SDHCI device emulation. A guest attacker could possibly     use this issue to cause QEMU to crash, leading to a denial of service. This issue only affected Ubuntu     22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-3447)

    It was discovered that QEMU incorrectly handled calculating the checksum of a short-sized fragmented     packet. A guest attacker could possibly use this issue to cause QEMU to crash, leading to a denial of     service. This issue only affected Ubuntu 24.04 LTS. (CVE-2024-3567)

    It was discovered that the QEMU qemu-img utility incorrectly handled certain crafted image files. An     attacker could use this issue to cause QEMU to consume resources, leading to a denial of service, or     possibly read and write to an existing external file. This issue only affected Ubuntu 22.04 LTS and Ubuntu     24.04 LTS. (CVE-2024-4467)

    It was discovered that QEMU incorrectly handled the RSS feature on virtio-net devices. A privileged guest     attacker could possibly use this issue to cause QEMU to crash, leading to a denial of service. This issue     only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-6505)

    It was discovered that QEMU incorrectly handled the NBD server. An attacker could use this issue to cause     QEMU to consume resources, leading to a denial of service. This issue only affected Ubuntu 22.04 LTS and     Ubuntu 24.04 LTS. (CVE-2024-7409)

    It was discovered that QEMU incorrectly handled certain USB devices. A guest attacker could possibly use     this issue to cause QEMU to crash, leading to a denial of service. This issue only affected Ubuntu 22.04     LTS and Ubuntu 24.04 LTS. (CVE-2024-8354)

    It was discovered that the QEMU package incorrectly set up a binfmt_misc registration with the C     (Credential) flag. A local attacker could use this with a suid/sgid binary to escalate privileges. This     update will no longer run foreign-architecture binaries with suid/sgid with elevated privileges.
