NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby:3.3/rubygem-power_assert package and not the ruby:3.3/rubygem-power_assert package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 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.
