AMD64 x86 emulation GTK+ library: User-assisted execution of arbitrary code


1.  Gentoo Linux Security Advisory

Version Information

Advisory Reference GLSA 200712-24 / emul-linux-x86-gtklibs
Release Date December 30, 2007
Latest Revision December 30, 2007: 01
Impact normal
Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)

Related bugreports: #201860


Multiple integer overflow vulnerabilities in the AMD64 x86 emulation GTK+ libraries may result in the execution of arbitrary code in applications using Cairo.

2.  Impact Information


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).


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.

3.  Resolution Information


There is no known workaround at this time.


All AMD64 x86 emulation GTK+ library users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-emulation/emul-linux-x86-gtklibs-20071214"
