    CVE-2021-3909

    Published: 11 Nov 2021Last Modified: 8 Jul 2026

    Summary:

    Details: 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.
