    Package        : freeswan
    Vulnerability  : denial of service
    Problem-type   : remore
    Debian-specific: no
    CERT advisory  : VU#459371
    
    Bindview discovered a problem in several IPSEC implementations that do
    not properly handle certain very short packets.  IPSEC is a set of
    security extensions to IP which provide authentication and encryption.
    Free/SWan in Debain is affected by this and is said to cause a kernel
    panic.
    
    This problem has been fixed in version 1.96-1.4 for the current stable
    distribution (woody) and in version 1.99-1 for the unstable
    distribution (sid).  The old stable distribution (potato) does not
    contain Free/SWan packages.
    
    We recommend that you upgrade your freeswan package.
    
    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.
