  <title>Portage, Gentoolkit: Temporary file vulnerabilities</title>
  <synopsis>
    dispatch-conf (included in Portage) and qpkg (included in Gentoolkit) are
    vulnerable to symlink attacks, potentially allowing a local user to
    overwrite arbitrary files with the rights of the user running the script.

  <background>
    <p>
    Portage is Gentoo's package management tool. The dispatch-conf utility
    allows for easy rollback of configuration file changes and automatic
    updates of configurations files never modified by users. Gentoolkit is
    a collection of Gentoo specific administration scripts, one of which is
    the portage querying tool qpkg.
    </p>
  </background>
  <description>
    <p>
    dispatch-conf and qpkg use predictable filenames for temporary files.
    </p>
  </description>
  <impact type="normal">
    <p>
    A local attacker could create symbolic links in the temporary files
    directory, pointing to a valid file somewhere on the filesystem. When
    an affected script is called, this would result in the file to be
    overwritten with the rights of the user running the dispatch-conf or
    qpkg, which could be the root user.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Portage users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=sys-apps/portage-2.0.51-r3"</code>
    <p>
    All Gentoolkit users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-portage/gentoolkit-0.2.0_pre8-r1"</code>
  </resolution>
