    Package: ntp
    Vulnerability: remote root exploit
    Debian-specific: no
    Przemyslaw Frasunek <This email address is being protected from spambots. You need JavaScript enabled to view it.> reported that ntp
    daemons such as that released with Debian GNU/Linux are vulnerable to a
    buffer overflow that can lead to a remote root exploit. A previous
    advisory (DSA-045-1) partially addressed this issue, but introduced a
    potential denial of service attack. This has been corrected for Debian
    2.2 (potato) in ntp version 4.0.99g-2potato2.
    We recommend you upgrade your ntp package immediately.
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    You may use an automated update by adding the resources from the
    footer to the proper configuration.
