GLSA 200712-24: AMD64 x86 emulation GTK+ library: User-assisted execution of arbitrary code

Severity:	normal
Title:	AMD64 x86 emulation GTK+ library: User-assisted execution of arbitrary code
Date:	12/30/2007
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	Architecture(s)
app-emulation/emul-linux-x86-gtklibs	< 20071214	>= 20071214	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:

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