Title:	Graphite: User-assisted execution of arbitrary code
Date:	06/22/2017
Bugs:	#616034
ID:	201706-25

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	Architecture(s)
media-gfx/graphite2	< 1.3.8-r1	>= 1.3.8-r1	All supported architectures

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"
