  <affected>
    <package name="dev-util/valgrind" auto="yes" arch="*">

    <p>
    Tavis Ormandy reported that Valgrind loads a .valgrindrc file in the
    current working directory, executing commands specified there.
    </p>
  </description>
  <impact type="high">
    <p>
    A local attacker could prepare a specially crafted .valgrindrc file and
    entice a user to run Valgrind from the directory containing that file,
    resulting in the execution of arbitrary code with the privileges of the
    user running Valgrind.
    </p>
  </impact>
  <workaround>
    <p>
    Do not run "valgrind" from untrusted working directories.
    </p>
  </workaround>
  <resolution>
    <p>
    All Valgrind users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-util/valgrind-3.4.0&quot;</code>
  </resolution>
