CVE-2023-46317

Summary

CVE-2023-46317 is a vulnerability affecting the Knot Resolver software before version 5.7.0. This issue arises due to the resolver's behavior in responding to nonsensical server responses, leading it to perform excessive TCP reconnections. These repeated attempts to connect to servers can result in increased network traffic and potentially hinder the overall performance of DNS services. Attackers could exploit this vulnerability to trigger these unnecessary reconnections, causing potential denial-of-service (DoS) conditions or other unintended consequences. It is recommended that users update to the latest version of Knot Resolver to mitigate this risk.
