"The remote NewStart CGSL host, running version MAIN 7.02, has qemu packages installed that are affected by multiple
vulnerabilities:

  - A stack based buffer overflow was found in the virtio-net device of QEMU. This issue occurs when flushing
    TX in the virtio_net_flush_tx function if guest features VIRTIO_NET_F_HASH_REPORT, VIRTIO_F_VERSION_1 and
    VIRTIO_NET_F_MRG_RXBUF are enabled. This could allow a malicious user to overwrite local variables
    allocated on the stack. Specifically, the `out_sg` variable could be used to read a part of process memory
    and send it to the wire, causing an information leak. (CVE-2023-6693)

  - A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. The
    qemu_clipboard_request() function can be reached before vnc_server_cut_text_caps() was called and had the
    chance to initialize the clipboard peer, leading to a NULL pointer dereference. This could allow a
    malicious authenticated VNC client to crash QEMU and trigger a denial of service. (CVE-2023-6683)

  - A double free vulnerability was found in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio-
    crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. This
    issue could allow a malicious privileged guest user to crash the QEMU process on the host, resulting in a
    denial of service or allow arbitrary code execution within the context of the QEMU process on the host.
    (CVE-2024-3446)

  - A heap buffer overflow was found in the virtio-snd device in QEMU. When reading input audio in the virtio-
    snd input callback, virtio_snd_pcm_in_cb, the function did not check whether the iov can fit the data
    buffer. This issue can trigger an out-of-bounds write if the size of the virtio queue element is equal to
    virtio_snd_pcm_status, which makes the available space for audio data zero. (CVE-2024-7730)

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