FreeBSD : net/krill -- DoS vulnerability (7844789a-9b1f-11ed-9a3f-b42e991fc52e)

high Nessus Plugin ID 170398



The remote FreeBSD host is missing one or more security-related updates.


The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 7844789a-9b1f-11ed-9a3f-b42e991fc52e advisory.

- NLnet Labs Krill supports direct access to the RRDP repository content through its built-in web server at the /rrdp endpoint. Prior to 0.12.1 a direct query for any existing directory under /rrdp/, rather than an RRDP file such as /rrdp/notification.xml as would be expected, causes Krill to crash. If the built-in /rrdp endpoint is exposed directly to the internet, then malicious remote parties can cause the publication server to crash. The repository content is not affected by this, but the availability of the server and repository can cause issues if this attack is persistent and is not mitigated. (CVE-2023-0158)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Update the affected packages.
