How to fix?

Upgrade Minimos:latest ruby-3.2-doc to version 3.2.9-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby-3.2-doc package and not the ruby-3.2-doc package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

The attack vector is a potential Denial of Service (DoS). The vulnerability is caused by an insufficient check on the length of a decompressed domain name within a DNS packet.

An attacker can craft a malicious DNS packet containing a highly compressed domain name. When the resolv library parses such a packet, the name decompression process consumes a large amount of CPU resources, as the library does not limit the resulting length of the name.

This resource consumption can cause the application thread to become unresponsive, resulting in a Denial of Service condition.
