Hi,
The following vulnerability was published for dnsdist.
CVE-2025-30187[0]:
| In some circumstances, when DNSdist is configured to use the nghttp2
| library to process incoming DNS over HTTPS queries, an attacker
| might be able to cause a denial of service by crafting a DoH
| exchange that triggers an unbounded I/O read loop, causing an
| unexpected consumption of CPU resources.
If you fix the vulnerability please also make sure to include the
