CVE-2024-56946

Name of the Vulnerable Software and Affected Versions Technitium DNS Server versions <= 13.2.2

Description The issue allows remote attackers to permanently stop the server from accepting new DNS-over-QUIC connections by triggering unhandled exceptions in listener threads. This can lead to a denial of service in DNS-over-QUIC.

Recommendations For Technitium DNS Server versions <= 13.2.2, update to a version higher than 13.2.2 to resolve the issue. As a temporary workaround, consider restricting access to the DNS-over-QUIC functionality until a patch is available.
