summary 
resolv vulnerable to DoS via insufficient DNS domain name length validation
A denial of service vulnerability has been discovered in the resolv gem bundled with Ruby.

## Details
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.

## Affected Version
The vulnerability affects the resolv gem bundled with the following Ruby series:
* Ruby 3.2 series: resolv version 0.2.2 and earlier
* Ruby 3.3 series: resolv version 0.3.0
* Ruby 3.4 series: resolv version 0.6.1 and earlier

## Credits
Thanks to Manu for discovering this issue.
