"The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as
referenced in the SUSE-SU-2024:1395-1 advisory.

  - A DMA reentrancy issue was found in the USB EHCI controller emulation of QEMU. EHCI does not verify if the
    Buffer Pointer overlaps with its MMIO region when it transfers the USB packets. Crafted content may be
    written to the controller's registers and trigger undesirable actions (such as reset) while the device is
    still transferring packets. This can ultimately lead to a use-after-free issue. A malicious guest could
    use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or
    potentially execute arbitrary code within the context of the QEMU process on the host. This flaw affects
    QEMU versions before 7.0.0. (CVE-2021-3750)

  - 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)

  - A vulnerability in the lsi53c895a device affects the latest version of qemu. A DMA-MMIO reentrancy problem
    may lead to memory corruption bugs like stack overflow or use-after-free. (CVE-2023-0330)

  - A flaw was found in the QEMU virtual crypto device while handling data encryption/decryption requests in
    virtio_crypto_handle_sym_req. There is no check for the value of `src_len` and `dst_len` in
    virtio_crypto_sym_op_helper, potentially leading to a heap buffer overflow when the two values differ.
    (CVE-2023-3180)

  - A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks
    whether the current number of connections crosses a certain threshold and if so, cleans up the previous
    connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the
    connection again, resulting in a NULL pointer dereference issue. This could allow a remote unauthenticated
    client to cause a denial of service. (CVE-2023-3354)

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