NVD Description

Note: Versions mentioned in the description apply to the upstream fort-validator package. See How to fix? for Debian:12 relevant versions.

OctoRPKI does not limit the length of a connection, allowing for a slowloris DOS attack to take place which makes OctoRPKI wait forever. Specifically, the repository that OctoRPKI sends HTTP requests to will keep the connection open for a day before a response is returned, but does keep drip feeding new bytes to keep the connection alive.
