title: Possible Denial of Service in resolv gem
date: 2025-07-08
description: |
A denial of service vulnerability has been discovered in the `resolv` gem bundled with Ruby.

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.
