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

  - The ahci_commit_buf function in ide/ahci.c in QEMU allows attackers to cause a denial of service (NULL     dereference) when the command header 'ad->cur_cmd' is null. (CVE-2019-12067)

  - hw/pci/msix.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access via a crafted address     in an msi-x mmio operation. (CVE-2020-13754)

  - QEMU 5.0.0 has a heap-based Buffer Overflow in flatview_read_continue in exec.c because hw/sd/sdhci.c     mishandles a write operation in the SDHC_BLKSIZE case. (CVE-2020-25085)

  - pci_change_irq_level in hw/pci/pci.c in QEMU before 5.1.1 has a NULL pointer dereference because     pci_get_bus() might not return a valid pointer. (CVE-2020-25742)

  - hw/ide/pci.c in QEMU before 5.1.1 can trigger a NULL pointer dereference because it lacks a pointer check     before an ide_cancel_dma_sync call. (CVE-2020-25743)

  - eth_get_gso_type in net/eth.c in QEMU 4.2.1 allows guest OS users to trigger an assertion failure. A guest     can crash the QEMU process via packet data that lacks a valid Layer 3 protocol. (CVE-2020-27617)

  - A flaw was found in the memory management API of QEMU during the initialization of a memory region cache.
    This issue could lead to an out-of-bounds write access to the MSI-X table while performing MMIO     operations. A guest user may abuse this flaw to crash the QEMU process on the host, resulting in a denial     of service. This flaw affects QEMU versions prior to 5.2.0. (CVE-2020-27821)

  - ncsi.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of     header data even if that exceeds the total packet length. (CVE-2020-29129)

  - ide_atapi_cmd_reply_end in hw/ide/atapi.c in QEMU 5.1.0 allows out-of-bounds read access because a buffer     index is not validated. (CVE-2020-29443)

  - A NULL pointer dereference flaw was found in the SCSI emulation support of QEMU in versions before 6.0.0.
    This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of     service. The highest threat from this vulnerability is to system availability. (CVE-2020-35504)

  - A NULL pointer dereference flaw was found in the am53c974 SCSI host bus adapter emulation of QEMU in     versions before 6.0.0. This issue occurs while handling the 'Information Transfer' command. This flaw     allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service.
    The highest threat from this vulnerability is to system availability. (CVE-2020-35505)

  - A race condition flaw was found in the 9pfs server implementation of QEMU up to and including 5.2.0. This     flaw allows a malicious 9p client to cause a use-after-free error, potentially escalating their privileges     on the system. The highest threat from this vulnerability is to confidentiality, integrity as well as     system availability. (CVE-2021-20181)

  - An integer overflow issue was found in the vmxnet3 NIC emulator of the QEMU for versions up to v5.2.0. It     may occur if a guest was to supply invalid values for rx/tx queue size or other NIC parameters. A     privileged guest user may use this flaw to crash the QEMU process on the host resulting in DoS scenario.
    (CVE-2021-20203)

  - An out-of-bounds heap buffer access issue was found in the ARM Generic Interrupt Controller emulator of     QEMU up to and including qemu 4.2.0on aarch64 platform. The issue occurs because while writing an     interrupt ID to the controller memory area, it is not masked to be 4 bits wide. It may lead to the said     issue while updating controller state fields and their subsequent processing. A privileged guest user may     use this flaw to crash the QEMU process on the host resulting in DoS scenario. (CVE-2021-20221)

  - A use-after-free flaw was found in the MegaRAID emulator of QEMU. This issue occurs while processing SCSI     I/O requests in the case of an error mptsas_free_request() that does not dequeue the request object 'req'     from a pending requests queue. This flaw allows a privileged guest user to crash the QEMU process on the     host, resulting in a denial of service. Versions between 2.10.0 and 5.2.0 are potentially affected.
    (CVE-2021-3392)

  - A potential stack overflow via infinite loop issue was found in various NIC emulators of QEMU in versions     up to and including 5.2.0. The issue occurs in loopback mode of a NIC wherein reentrant DMA checks get     bypassed. A guest user/process may use this flaw to consume CPU cycles or crash the QEMU process on the     host resulting in DoS scenario. (CVE-2021-3416)

  - A flaw was found in the USB redirector device (usb-redir) of QEMU. Small USB packets are combined into a     single, large transfer request, to reduce the overhead and improve performance. The combined size of the     bulk transfer is used to dynamically allocate a variable length array (VLA) on the stack without proper     validation. Since the total size is not bounded, a malicious guest could use this flaw to influence the     array length and cause the QEMU process to perform an excessive allocation on the stack, resulting in a     denial of service. (CVE-2021-3527)

  - Several memory leaks were found in the virtio vhost-user GPU device (vhost-user-gpu) of QEMU in versions     up to and including 6.0. They exist in contrib/vhost-user-gpu/vhost-user-gpu.c and contrib/vhost-user-     gpu/virgl.c due to improper release of memory (i.e., free) after effective lifetime. (CVE-2021-3544)

  - An information disclosure vulnerability was found in the virtio vhost-user GPU device (vhost-user-gpu) of     QEMU in versions up to and including 6.0. The flaw exists in virgl_cmd_get_capset_info() in contrib/vhost-     user-gpu/virgl.c and could occur due to the read of uninitialized memory. A malicious guest could exploit     this issue to leak memory from the host. (CVE-2021-3545)

  - An out-of-bounds write vulnerability was found in the virtio vhost-user GPU device (vhost-user-gpu) of     QEMU in versions up to and including 6.0. The flaw occurs while processing the 'VIRTIO_GPU_CMD_GET_CAPSET'     command from the guest. It could allow a privileged guest user to crash the QEMU process on the host,     resulting in a denial of service condition, or potential code execution with the privileges of the QEMU     process. (CVE-2021-3546)

  - An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw     exists in the bootp_input() function and could occur while processing a udp packet that is smaller than     the size of the 'bootp_t' structure. A malicious guest could use this flaw to leak 10 bytes of     uninitialized heap memory from the host. The highest threat from this vulnerability is to data     confidentiality. This flaw affects libslirp versions prior to 4.6.0. (CVE-2021-3592)

  - An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw     exists in the udp6_input() function and could occur while processing a udp packet that is smaller than the     size of the 'udphdr' structure. This issue may lead to out-of-bounds read access or indirect host memory     disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw     affects libslirp versions prior to 4.6.0. (CVE-2021-3593)

  - An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw     exists in the tftp_input() function and could occur while processing a udp packet that is smaller than the     size of the 'tftp_t' structure. This issue may lead to out-of-bounds read access or indirect host memory     disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw     affects libslirp versions prior to 4.6.0. (CVE-2021-3595)

  - A flaw was found in the USB redirector device emulation of QEMU in versions prior to 6.1.0-rc2. It occurs     when dropping packets during a bulk transfer from a SPICE client due to the packet queue being full. A     malicious SPICE client could use this flaw to make QEMU call free() with faked heap chunk metadata,     resulting in a crash of QEMU or potential code execution with the privileges of the QEMU process on the     host. (CVE-2021-3682)

  - An out-of-bounds write flaw was found in the UAS (USB Attached SCSI) device emulation of QEMU in versions     prior to 6.2.0-rc0. The device uses the guest supplied stream number unchecked, which can lead to out-of-     bounds access to the UASDevice->data3 and UASDevice->status3 fields. A malicious guest user could use this     flaw to crash QEMU or potentially achieve code execution with the privileges of the QEMU process on the     host. (CVE-2021-3713)
