    It has been discovered that NTP, an implementation of the Network Time Protocol, does not properly check the result of an OpenSSL function for verifying cryptographic signatures, which may ultimately lead to the acceptance of unauthenticated time information. (Note that

    Debian Bug     : 511227
    
    It has been discovered that NTP, an implementation of the Network Time
    Protocol, does not properly check the result of an OpenSSL function
    for verifying cryptographic signatures, which may ultimately lead to
    the acceptance of unauthenticated time information.  (Note that
    cryptographic authentication of time servers is often not enabled in
    the first place.)
    
    For the stable distribution (etch), this problem has been fixed in
    version 4.2.2.p4+dfsg-2etch1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 4.2.4p4+dfsg-8.
    
    The testing distribution (lenny) will be fixed soon.
    
    We recommend that you upgrade your ntp package.
    
    Upgrade instructions
    - --------------------
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    
    If you are using the apt-get package manager, use the line for
    sources.list as given below:
    
    apt-get update
            will update the internal database
    apt-get upgrade
            will install corrected packages
    
    You may use an automated update by adding the resources from the
    footer to the proper configuration.

      These files will probably be moved into the stable distribution on
      its next update.
