# [PowerDNS DNSdist 1.9.9 released, fixing CVE-2025-30194](https://blog.powerdns.com/2025/04/29/powerdns-dnsdist-1.9.9-released)

We released PowerDNS DNSdist 1.9.9 today, an emergency release fixing a security issue tracked as CVE-2025-30194 where a remote, unauthenticated attacker can cause a denial of service via a crafted DNS over HTTPS connection. The issue was reported to us via our public GitHub tracker, so once it was clear that the issue had a security impact we prepared to release a new version as soon as possible.

While we advise upgrading to a fixed version, a work-around is to temporarily switch to the h2o provider until DNSdist has been upgraded.

Please see the DNSdist [website](https://dnsdist.org/) for the [changelog](https://dnsdist.org/changelog.html#change-1.9.9) and the current documentation.

Please send us all feedback and issues you might have via the [mailing list](https://mailman.powerdns.com/mailman/listinfo/dnsdist), or in case of a bug, via [GitHub](https://github.com/PowerDNS/pdns/issues/new/choose).

The release [tarball](https://downloads.powerdns.com/releases/dnsdist-1.9.9.tar.bz2) and its [signature](https://downloads.powerdns.com/releases/dnsdist-1.9.9.tar.bz2.sig) are available on the downloads website, and packages for several distributions are available from our [repository](https://repo.powerdns.com/).
