<title>AMD64 x86 emulation GTK+ library: User-assisted execution of arbitrary code</title>
<synopsis>

<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.

<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>
