    Package        : sudo
    Problem type   : buffer overflow
    Debian-specific: no
    
    fc found a buffer overflow in the variable expansion code
    used by sudo for its prompt. Since sudo is necessarily installed suid
    root a local user can use this to gain root access.
    
    This has been fixed in version 1.6.2-2.2 and we recommend that you upgrade
    your sudo package immediately.
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
