Synopsis
========

An out-of-bounds write in Graphite might allow remote attackers to
execute arbitrary code.

Background
==========

Graphite is a "smart font" system developed specifically to handle the
complexities of lesser-known languages of the world.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/graphite2 < 1.3.8-r1 >= 1.3.8-r1

Description
===========

An out-of-bounds write has been found in the Graphite 2 library.

Impact
======

A remote attacker could entice a user to open a specially crafted
document using Graphite or an application linked against Graphite
library, possibly resulting in execution of arbitrary code with the
privileges of the process or a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Graphite users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose
">=media-gfx/graphite2-1.3.8-r1"

References
==========
