The remote SUSE Linux SLES11 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:14704-1 advisory.

  - The vmware-vga driver (hw/display/vmware_vga.c) in QEMU allows local guest users to write to qemu memory     locations and gain privileges via unspecified parameters related to rectangle handling. (CVE-2014-3689)

  - The VNC websocket frame decoder in QEMU allows remote attackers to cause a denial of service (memory and     CPU consumption) via a large (1) websocket payload or (2) HTTP headers section. (CVE-2015-1779)

  - In QEMU through 5.0.0, an integer overflow was found in the SM501 display driver implementation. This flaw     occurs in the COPY_AREA macro while handling MMIO write operations through the sm501_2d_engine_write()     callback. A local attacker could abuse this flaw to crash the QEMU process in sm501_2d_operation() in     hw/display/sm501.c on the host, resulting in a denial of service. (CVE-2020-12829)

  - In QEMU 5.0.0 and earlier, es1370_transfer_audio in hw/audio/es1370.c does not properly validate the frame     count, which allows guest OS users to trigger an out-of-bounds access during an es1370_write() operation.
    (CVE-2020-13361)

  - In QEMU 5.0.0 and earlier, megasas_lookup_frame in hw/scsi/megasas.c has an out-of-bounds read via a     crafted reply_queue_head field from a guest OS user. (CVE-2020-13362)

  - rom_copy() in hw/core/loader.c in QEMU 4.0 and 4.1.0 does not validate the relationship between two     addresses, which allows attackers to trigger an invalid memory copy operation. (CVE-2020-13765)

  - 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)

  - QEMU 5.0.0 has a use-after-free in hw/usb/hcd-xhci.c because the usb_packet_map return value is not     checked. (CVE-2020-25084)

  - hw/usb/hcd-ohci.c in QEMU 5.0.0 has a stack-based buffer over-read via values obtained from the host     controller driver. (CVE-2020-25624)

  - hw/usb/hcd-ohci.c in QEMU 5.0.0 has an infinite loop when a TD list has a loop. (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)

  - slirp.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-2020-29130)

  - 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 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)

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