Synopsis
========
Multiple integer overflows were discovered in Cairo,
possibly leading
to the execution of arbitrary code.
Background
==========
Cairo is a 2D vector graphics library with cross-device
output support.
Affected packages
=================
------------------------------------------------------------
-------
Package / Vulnerable /
Unaffected
------------------------------------------------------------
-------
1 x11-libs/cairo < 1.4.12
>= 1.4.12
Description
===========
Multiple integer overflows were reported, one of which Peter
Valchev
(Google Security) found to be leading to a heap-based buffer
overflow
in the cairo_image_surface_create_from_png() function that
processes
PNG images.
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 Cairo users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose
">=x11-libs/cairo-1.4.12"
References
==========
