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

  - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security
advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
