The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3768-1 advisory.

  - A heap-based buffer overflow was found in QEMU through 5.0.0 in the SDHCI device emulation support. It     could occur while doing a multi block SDMA transfer via the sdhci_sdma_transfer_multi_blocks() routine in     hw/sd/sdhci.c. A guest user or process could use this flaw to crash the QEMU process on the host,     resulting in a denial of service condition, or potentially execute arbitrary code with privileges of the     QEMU process on the host. (CVE-2020-17380)

  - The patch for CVE-2020-17380/CVE-2020-25085 was found to be ineffective, thus making QEMU vulnerable to     the out-of-bounds read/write access issues previously found in the SDHCI controller emulation code. This     flaw allows a malicious privileged guest to crash the QEMU process on the host, resulting in a denial of     service or potential code execution. QEMU up to (including) 5.2.0 is affected by this. (CVE-2021-3409)

  - 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 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)

  - ** DISPUTED ** 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)

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