Subject Name:            ProFTPD
Subject Summary:         Professional FTP Daemon
Subject Home:            http://www.proftpd.net/
Subject Versions:        * <= 1.2.9

Vulnerability Id:        none
Vulnerability Scope:     global (not OpenPKG specific)

Attack Feasibility:      run-time
Attack Vector:           remote network
Attack Impact:           privilege escalation

Description:
    A portability workaround was applied in version 1.2.9 of the FTP
    server ProFTPD [1]. As a side-effect, CIDR based (aaa.bbb.ccc.ddd/NN)
    ACL entries in "Allow" and "Deny" directives act like an "AllowAll"
    directive and so FTP clients are granted access to files and
    directories although the server configuration might explicitly deny
    this [2].
