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

  - A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client
    had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or
    printer) instead of client-supplied data. The client cannot control the area of the server memory written
    to the file (or printer). (CVE-2022-32742)

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.");
