    A buffer overflow vulnerability has been found in the
    linux-ftpd-ssl package. A command that generates an excessively long
    response from the server may overrun a stack buffer.
  
Impact :

    An attacker that has permission to create directories that are
    accessible via the FTP server could exploit this vulnerability.
    Successful exploitation would execute arbitrary code on the local
    machine with root privileges.
  
Workaround :

    There is no known workaround at this time."
