    <p>
    libXpm is a pixmap manipulation library for the X Window System,
    included in both X.Org and XFree86.
    </p>
  </background>
  <description>
    <p>
    Several issues were discovered in libXpm, including integer
    overflows, out-of-bounds memory accesses, insecure path traversal and
    an endless loop.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could craft a malicious pixmap file and entice a user
    to use it with an application linked against libXpm. This could lead to
    Denial of Service or arbitrary code execution.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All X.Org users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=x11-base/xorg-x11-6.7.0-r3&quot;</code>
    <p>
    All XFree86 users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=x11-base/xfree-x11-4.3.0-r8&quot;</code>
