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

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.
The Cairo versions used by the AMD64 x86 emulation GTK+ libraries were
vulnerable to integer overflow vulnerabilities (GLSA 200712-04).
<impact type="normal">
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.
There is no known workaround at this time.
All AMD64 x86 emulation GTK+ library users should upgrade to the latest
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-emulation/emul-linux-x86-gtklibs-20071214&quot;</code>
