    Package        : sendfile
    Vulnerability  : broken privileges dropping
    Problem-Type   : local root exploit
    Debian-specific: no
    
    Daniel Kobras has discovered and fixed a problem in sendfiled which
    caused the daemon not to drop privileges as expected when sendnig
    notification mails.  Exploiting this a local user can easily make it
    execute arbitrary code under root privileges.
    
    We recommend that you upgrade your sendfile packages immediately.
    
    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.
