Subject Name:            ProFTPD
Subject Summary:         Professional FTP Daemon
Subject Home:            http://www.proftpd.org/
Subject Versions:        * < 1.3.1rc1

Vulnerability Id:        CVE-2006-6563
Vulnerability Scope:     global (not OpenPKG specific)

Attack Feasibility:      run-time
Attack Vector:           remote network
Attack Impact:           denial of service, privilege escalation,
                         arbitrary code execution

Description:
    A vulnerability exists in the FTP server ProFTPD, versions up to
    and including 1.3.0a. 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.
