    Package        : mime-support
    Vulnerability  : insecure temporary file creation
    Problem-Type   : local
    Debian-specific: no
    
    Unfortunately yesterday's update for mime-support did not exactly work
    as expected, which requires an update.  For completeness we include
    the advisory text:
    
      Colin Phipps discovered several problems in mime-support, that contains
      support programs for the MIME control files 'mime.types' and 'mailcap'.
      When a temporary file is to be used it is created insecurely, allowing
      an attacker to overwrite arbitrary under the user id of the person
      executing run-mailcap, most probably root.  Additionally the program did
      not properly escape shell escape characters when executing a command.
      This is unlikely to be exploitable, though.
    
    For the stable distribution (woody) these problems have been fixed in
    version 3.18-1.2.
    
    For the old stable distribution (potato) these problems have been
    fixed in version 3.9-1.2.
    
    For the unstable distribution (sid) these problems have been
    fixed in version 3.22-1 (same as DSA 292-1).
    
    We recommend that you upgrade your mime-support packages.
    
    
    Upgrade Instructions

    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
