    Package        : wu-ftpd
    Problem type   : remote root exploit
    Debian-specific: no
    
    CORE ST reports that an exploit has been found for a bug in the wu-ftpd
    glob code (this is the code that handles filename wildcard expansion).
    Any logged in user (including anonymous ftp users) can exploit the bug
    to gain root privilege on the server.
    
    This has been corrected in version 2.6.0-6 of the wu-ftpd package.
    
    wget url
            will fetch the file for you
