    Debian-specific: no
    
    Basically, this is the same Security Advisory as DSA 102-1, except
    that the uploaded binary packages really fix the problem this time.
    Unfortunately the bugfix from DSA 102-1 wasn't propagated properly due
    to a packaging bug.  While the file parsetime.y was fixed, and
    yy.tab.c should be generated from it, yy.tab.c from the original
    source was still used.  This has been fixed now.
    
    The original advisory said:
    
    zen-parse found a bug in the current implementation of at which leads
    into a heap corruption vulnerability which in turn could potentially
    lead into an exploit of the daemon user.
    
    This has been fixed in at 3.1.8-10.2 for the stable Debian release and
    3.1.8-11 for the unstable and testing release.  Packages for unstable
    have just been uploaded into  <http://incoming.debian.org/>.  We
    recommend that you upgrade your at packages immediately since an
    exploit has already been published.
    
    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.
