"The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in
the SUSE-SU-2024:0589-1 advisory.

  - An out-of-bounds memory access flaw was found in the ATI VGA device emulation of QEMU. This flaw occurs in
    the ati_2d_blt() routine while handling MMIO write operations when the guest provides invalid values for
    the destination display parameters. A malicious guest could use this flaw to crash the QEMU process on the
    host, resulting in a denial of service. (CVE-2021-3638)

  - 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.");
