How to fix?

Upgrade Oracle:8 rubygem-pg to version 0:1.0.0-2.module+el8.3.0+7756+e45777e9 or higher.

NVD Description

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

An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. A malicious FTP server can use the PASV response to trick Net::FTP into connecting back to a given IP address and port. This potentially makes curl extract information about services that are otherwise private and not disclosed (e.g., the attacker can conduct port scans and service banner extractions).
