  <affected>
    <package name="sys-devel/pmake" auto="yes" arch="*">
      <unaffected range="ge">1.111.3.1</unaffected>

  <background>
    <p>pmake is Debian’s version of NetBSD’s make, a tool to build programs
      in parallel.
    </p>
  </background>
  <description>
    <p>/usr/share/mk/bsd.lib.mk and /usr/share/mk/bsd.prog.mk create temporary
      files insecurely, with predictable names (/tmp/_depend[PID]), and
      without using $TMPDIR.
    </p>
  </description>
  <impact type="low">
    <p>The make include files allow local users to overwrite arbitrary files
      via a symlink attack.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All pmake users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=sys-devel/pmake-1.111.3.1"
    </code>
