According to the version of the curl packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

  • This flaw can be mitigated in curl as shipped with Red Hat Enterprise Linux and Red Hat Software Collections when using curl by passing the --ftp-skip-pasv-ip command line option to curl. For usage of libcurl, set CURLOPT_FTP_SKIP_PASV_IP to 1L[1]. Note that these mitigations could cause probl(CVE-2020-8284)

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.
