    Colin Phipps and Daniel Kobras discovered and fixed several serious
    bugs in the saft daemon `sendfiled' which caused it to drop privileges
    incorrectly.  Exploiting this a local user can easily make it execute
    arbitrary code under root privileges.
    
    We recommend you upgrade your sendfile packages 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.
