  <description>
    <p>
    Hamid Ebadi discovered a boundary error in the
    intT1_EnvGetCompletePath() function which can lead to a buffer overflow
    when processing an overly long filename.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a font file with a
    specially crafted filename, possibly leading to the execution of
    arbitrary code with the privileges of the user running the application
    using T1Lib.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All T1Lib users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-libs/t1lib-5.0.2-r1"</code>
