How to fix?

Upgrade Oracle:8 libcurl to version 0:7.61.1-18.el8 or higher.
This issue was patched in ELSA-2021-1610.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libcurl package and not the libcurl package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

A malicious server can use the FTP PASV response to trick curl 7.73.0 and earlier into connecting back to a given IP address and port, and this way potentially make curl extract information about services that are otherwise private and not disclosed, for example doing port scanning and service banner extractions.
