    Package        : cron
    Vulnerability  : local insecure crontab handling
    Debian-specific: no
    
    The FreeBSD team has found a bug in the way new crontabs were handled
    which allowed malicious users to display arbitrary crontab files on
    the local system.  This only affects valid crontab files so can't be
    used to get access to /etc/shadow or something.  crontab files are not
    especially secure anyway, as there are other ways they can leak.  No
    passwords or similar sensitive data should be in there.
    
    We recommend you upgrade your cron packages.
    
    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.
