CVE-2020-8284  (opens in a new tab)
CWE-200  (opens in a new tab)

How to fix?

Upgrade Centos:8 libcurl to version 0:7.61.1-18.el8 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libcurl package and not the libcurl package as distributed by Centos. See How to fix? for Centos: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.
