According to the versions of the qemu package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device. This flaw allows a     crafted guest driver to execute HW commands when shared buffers are not yet allocated, potentially leading     to a use-after-free condition. (CVE-2022-1050)

  - A flaw was found in the QEMU Guest Agent service for Windows. A local unprivileged user may be able to     manipulate the QEMU Guest Agent's Windows installer via repair custom actions to elevate their privileges     on the system. (CVE-2023-0664)

  - A flaw was found in the 9p passthrough filesystem (9pfs) implementation in QEMU. The 9pfs server did not     prohibit opening special files on the host side, potentially allowing a malicious client to escape from     the exported 9p tree by creating and opening a device file in the shared folder. (CVE-2023-2861)

  - 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)
