NVD reports :
ProFTPD ... controls whether the home directory of a user could
contain a symbolic link through the AllowChrootSymlinks configuration
option, but checks only the last path component when enforcing
AllowChrootSymlinks. Attackers with local access could bypass the
AllowChrootSymlinks control by replacing a path component (other than
the last one) with a symbolic link.
