Gentoo Linux Security Advisory

Title: AMD64 x86 emulation GTK+ library: User-assisted execution of arbitrary code (GLSA 200712-24)
Severity: normal
Exploitable: remote
Date: December 30, 2007
Bug(s): #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: app-emulation/emul-linux-x86-gtklibs
Vulnerable: < 20071214
Unaffected: >= 20071214
Architectures: amd64


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:
