    Debian Security Advisory DSA 292-2 security@debian.org

    - --------------------------------------------------------------------------

    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
    - --------------------

    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.
