  <title>AMD64 x86 emulation GTK+ library: User-assisted execution of arbitrary code</title>
  <synopsis>
    Multiple integer overflow vulnerabilities in the AMD64 x86 emulation GTK+
    libraries may result in the execution of arbitrary code in applications
    using Cairo.

    <p>
    Cairo is a 2D vector graphics library with cross-device output support.
    The AMD64 x86 emulation GTK+ library packages Cairo libraries for 32bit
    x86 emulation on AMD64.
    </p>

  <description>
    <p>
    The Cairo versions used by the AMD64 x86 emulation GTK+ libraries were
    vulnerable to integer overflow vulnerabilities (GLSA 200712-04).
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to view or process a specially
    crafted PNG image file in an application linked against Cairo, possibly
    leading to the execution of arbitrary code with the privileges of the
    user running the application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All AMD64 x86 emulation GTK+ library users should upgrade to the latest
    version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-emulation/emul-linux-x86-gtklibs-20071214&quot;</code>
