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

  - An infinite loop flaw was found in the USB xHCI controller emulation of QEMU while computing the length of     the Transfer Request Block (TRB) Ring. This flaw allows a privileged guest user to hang the QEMU process     on the host, resulting in a denial of service. (CVE-2020-14394)

  - A heap buffer overflow was found in the floppy disk emulator of QEMU up to 6.0.0 (including). It could     occur in fdctrl_transfer_handler() in hw/block/fdc.c while processing DMA read data transfers from the     floppy drive to the guest system. A privileged guest user could use this flaw to crash the QEMU process on     the host resulting in DoS scenario, or potential information leakage from the host memory. (CVE-2021-3507)

  - A stack overflow vulnerability was found in the Intel HD Audio device (intel-hda) of QEMU. A malicious     guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service     condition. The highest threat from this vulnerability is to system availability. This flaw affects QEMU     versions prior to 7.0.0. (CVE-2021-3611)

  - A DMA reentrancy issue was found in the USB EHCI controller emulation of QEMU. EHCI does not verify if the     Buffer Pointer overlaps with its MMIO region when it transfers the USB packets. Crafted content may be     written to the controller's registers and trigger undesirable actions (such as reset) while the device is     still transferring packets. This can ultimately lead to a use-after-free issue. A malicious guest could     use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or     potentially execute arbitrary code within the context of the QEMU process on the host. This flaw affects     QEMU versions before 7.0.0. (CVE-2021-3750)

  - A NULL pointer dereference issue was found in the ACPI code of QEMU. A malicious, privileged user within     the guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service     condition. (CVE-2021-4158)

  - A flaw was found in the QXL display device emulation in QEMU. An integer overflow in the cursor_alloc()     function can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer     overflow. This flaw allows a malicious privileged guest user to crash the QEMU process on the host or     potentially execute arbitrary code within the context of the QEMU process. (CVE-2021-4206)

  - A flaw was found in the QXL display device emulation in QEMU. A double fetch of guest controlled values     `cursor->header.width` and `cursor->header.height` can lead to the allocation of a small cursor object     followed by a subsequent heap-based buffer overflow. A malicious privileged guest user could use this flaw     to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU     process. (CVE-2021-4207)

  - A use-after-free vulnerability was found in the LSI53C895A SCSI Host Bus Adapter emulation of QEMU. The     flaw occurs while processing repeated messages to cancel the current SCSI request via the lsi_do_msgout     function. This flaw allows a malicious privileged user within the guest to crash the QEMU process on the     host, resulting in a denial of service. (CVE-2022-0216)

  - A flaw was found in the QEMU virtio-fs shared file system daemon (virtiofsd) implementation. This flaw is     strictly related to CVE-2018-13405. A local guest user can create files in the directories shared by     virtio-fs with unintended group ownership in a scenario where a directory is SGID to a certain group and     is writable by a user who is not a member of the group. This could allow a malicious unprivileged user     inside the guest to gain access to resources accessible to the root group, potentially escalating their     privileges within the guest. A malicious local user in the host might also leverage this unexpected     executable file created by the guest to escalate their privileges on the host system. (CVE-2022-0358)

  - A flaw was found in the virtio-net device of QEMU. This flaw was inadvertently introduced with the fix for     CVE-2021-3748, which forgot to unmap the cached virtqueue elements on error, leading to memory leakage and     other unexpected results. Affected QEMU version: 6.2.0. (CVE-2022-26353)

  - A flaw was found in the vhost-vsock device of QEMU. In case of error, an invalid element was not detached     from the virtqueue before freeing its memory, leading to memory leakage and other unexpected results.
    Affected QEMU versions <= 6.2.0. (CVE-2022-26354)

  - An integer underflow issue was found in the QEMU VNC server while processing ClientCutText messages in the     extended format. A malicious client could use this flaw to make QEMU unresponsive by sending a specially     crafted payload message, resulting in a denial of service. (CVE-2022-3165)

  - softmmu/physmem.c in QEMU through 7.0.0 can perform an uninitialized read on the translate_fail path,     leading to an io_readx or io_writex crash. NOTE: a third party states that the Non-virtualization Use Case     in the qemu.org reference applies here, i.e., 'Bugs affecting the non-virtualization use case are not     considered security bugs at this time. (CVE-2022-35414)

  - An off-by-one read/write issue was found in the SDHCI device of QEMU. It occurs when reading/writing the     Buffer Data Port Register in sdhci_read_dataport and sdhci_write_dataport, respectively, if data_count ==     block_size. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a     denial of service condition. (CVE-2022-3872)

  - An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt()     function does not check the size of the structure pointed to by the guest physical address, potentially     reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to     crash the QEMU process on the host causing a denial of service condition. (CVE-2022-4144)

  - A vulnerability in the lsi53c895a device affects the latest version of qemu. A DMA-MMIO reentrancy problem     may lead to memory corruption bugs like stack overflow or use-after-free. (CVE-2023-0330)

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.

    Package        : qemu     Version        : 1:3.1+dfsg-8+deb10u11     CVE ID         : CVE-2020-24165 CVE-2023-0330 CVE-2023-3180     Debian Bug     : 1029155

    Multiple issues were discovered in qemu, a fast processor emulator.

    CVE-2020-24165

        A use-after-free race in the code generator could lead to the         execution of arbitrary code.

    CVE-2023-0330

        A DMA-MMIO reentrancy problem in the lsi53c895a device may lead to         memory corruption bugs, such as stack overflow or use-after-free.

    CVE-2023-3180

        The function virtio_crypto_sym_op_helper, part of the implementation         of qemu's virtual crypto device, did not check that the values of         'src_len' and 'dst_len' are the same.  This could lead to a heap         buffer overflow.

    For Debian 10 buster, these problems have been fixed in version     1:3.1+dfsg-8+deb10u11.

    We recommend that you upgrade your qemu packages.
