  <title>Qt: Buffer overflow in the included zlib library</title>
  <synopsis>
    Qt is vulnerable to a buffer overflow which could potentially lead to the
    execution of arbitrary code.

    <p>
    Qt is a cross-platform GUI toolkit used by KDE.
    </p>

  <description>
    <p>
    Qt links to a bundled vulnerable version of zlib when emerged with the
    zlib USE-flag disabled. This may lead to a buffer overflow.
    </p>
  </description>
  <impact type="normal">
    <p>
    By creating a specially crafted compressed data stream, attackers can
    overwrite data structures for applications that use Qt, resulting in a
    Denial of Service or potentially arbitrary code execution.
    </p>
  </impact>
  <workaround>
    <p>
    Emerge Qt with the zlib USE-flag enabled.
    </p>
  </workaround>
  <resolution>
    <p>
    All Qt users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=x11-libs/qt-3.3.4-r8"</code>
  </resolution>
