arbitrary code
Date: December 30, 2007
Bugs: #201860
ID: 200712-24

Synopsis
========
Multiple integer overflow vulnerabilities in the AMD64 x86 emulation
GTK+ libraries may result in the execution of arbitrary code in
applications using Cairo.
Background
==========
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.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 emul-linux-x86-gtklibs lt; 20071214 gt;= 20071214
-------------------------------------------------------------------
# Package 1 only applies to AMD64 users.
Description
===========
The Cairo versions used by the AMD64 x86 emulation GTK+ libraries were
vulnerable to integer overflow vulnerabilities (GLSA 200712-04).
Impact
======
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.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All AMD64 x86 emulation GTK+ library users should upgrade to the latest
version:
# emerge --sync
# emerge -a -1 -v "gt;=app-emulation/emul-linux-x86-gtklibs-20071214"
