The remote Ubuntu 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6954-1 advisory.

    Markus Frank and Fiona Ebner discovered that QEMU did not properly handle certain memory operations,     leading to a NULL pointer dereference. An authenticated user could potentially use this issue to cause a     denial of service. (CVE-2023-6683)

    Xiao Lei discovered that QEMU did not properly handle certain memory

    operations when specific features were enabled, which could lead to a stack overflow. An attacker could     potentially use this issue to leak sensitive information. (CVE-2023-6693)

    It was discovered that QEMU had an integer underflow vulnerability in

    the TI command, which would result in a buffer overflow. An attacker could potentially use this issue to     cause a denial of service.

    - kvm-target-i386-fix-feature-dependency-for-WAITPKG.patch [RHEL-84866]

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. A wrong exit     condition may lead to an infinite loop when inflating an attacker controlled zlib buffer in the     `inflate_buffer` function. This could allow a remote authenticated client who is able to send a clipboard     to the VNC server to trigger a denial of service. (CVE-2023-3255)

  - A flaw was found in QEMU. The async nature of hot-unplug enables a race scenario where the net device     backend is cleared before the virtio-net pci frontend has been unplugged. A malicious guest could use this     time window to trigger an assertion and cause a denial of service. (CVE-2023-3301)

  - 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.

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:2962 advisory.

    Kernel-based Virtual Machine (KVM) offers a full virtualization solution for Linux on numerous hardware     platforms. The virt:rhel module contains packages which provide user-space components used to run virtual     machines using KVM. The packages also provide APIs for managing and interacting with the virtualized     systems.

    Security Fix(es):

    * QEMU: VNC: infinite loop in inflate_buffer() leads to denial of service (CVE-2023-3255)

    * QEMU: improper IDE controller reset can lead to MBR overwrite (CVE-2023-5088)

    * QEMU: VNC: NULL pointer dereference in qemu_clipboard_request() (CVE-2023-6683)

    * QEMU: virtio-net: stack buffer overflow in virtio_net_flush_tx() (CVE-2023-6693)
