The vulnerability is caused by a stack-based buffer overflow in the "pr_ctrls_recv_request" function of the "Controls" feature. This is an optional feature of ProFTPD server which is by default disabled in OpenPKG and that must be explicitly activated with the "with_ctrls" build-time option of the OpenPKG "profptd" package. Controls are a way to communicate directly with a standalone ProFTPD daemon while it is running. This provides administrators a way to alter the daemon's behavior in real time, without having to restart the daemon and have it re-read its configuration. The Controls feature allows authorized users to locally manage parameters of the ProFTPD servers, like aborting connections, managing users, changing log levels, disabling individual virtual servers, etc. The vulnerability allows local attackers with access to the Controls features (and who have been allowed by Controls ACLs in "proftpd.conf") to execute arbitrary code or even gain root privileges.
