CVE-2025-30194
Denial of service via crafted DoH exchange
Résumé
Denial of service via crafted DoH exchange
Description d'origine
La description telle que publiée par la source (souvent en anglais).
When DNSdist is configured to provide DoH via the nghttp2 provider, an attacker can cause a denial of service by crafting a DoH exchange that triggers an illegal memory access (double-free) and crash of DNSdist, causing a denial of service.
The remedy is: upgrade to the patched 1.9.9 version.
A workaround is to temporarily switch to the h2o provider until DNSdist has been upgraded to a fixed version.
We would like to thank Charles Howes for bringing this issue to our attention.
