  <title>eix: Insecure temporary file creation</title>
  <synopsis>
    eix has an insecure temporary file creation vulnerability, potentially
    allowing a local user to overwrite arbitrary files.

  <background>
    <p>
    eix is a small utility for searching ebuilds with indexing for fast
    results.

  <description>
    <p>
    Eric Romang discovered that eix creates a temporary file with a
    predictable name. eix creates a temporary file in /tmp/eix.*.sync where
    * is the process ID of the shell running eix.
    </p>
  </description>
  <impact type="normal">
    <p>
    A local attacker can watch the process list and determine the process
    ID of the shell running eix while the "emerge --sync" command is
    running, then create a link from the corresponding temporary file to a
    system file, which would result in the file being overwritten with the
    rights of the user running the application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All eix users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose app-portage/eix</code>
  </resolution>
