Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - QEMU: net: ignore packets with large size (CVE-2018-17963)

  - Buffer overflow in the send_control_msg function in hw/char/virtio-serial-bus.c in QEMU before 2.4.0     allows guest users to cause a denial of service (QEMU process crash) via a crafted virtio control message.
    (CVE-2015-5745)

  - The ehci_process_itd function in hw/usb/hcd-ehci.c in QEMU allows local guest OS administrators to cause a     denial of service (infinite loop and CPU consumption) via a circular isochronous transfer descriptor (iTD)     list. (CVE-2015-8558)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - QEMU: net: ignore packets with large size (CVE-2018-17963)

  - Buffer overflow in the send_control_msg function in hw/char/virtio-serial-bus.c in QEMU before 2.4.0     allows guest users to cause a denial of service (QEMU process crash) via a crafted virtio control message.
    (CVE-2015-5745)

  - The MSI-X MMIO support in hw/pci/msix.c in QEMU (aka Quick Emulator) allows local guest OS privileged     users to cause a denial of service (NULL pointer dereference and QEMU process crash) by leveraging failure     to define the .write method. (CVE-2015-7549)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
