Vulnerability from github – Published: 2025-09-18 12:30 – Updated: 2025-11-05 00:31

Details

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.

Severity ?

3.7 (Low)
