Gentoo Linux Security Advisory

Title: Graphite: User-assisted execution of arbitrary code (GLSA 201706-25)
Severity: normal
Exploitable: remote
Date: 2017-06-22
Bug(s): #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: media-gfx/graphite2
Vulnerable: < 1.3.8-r1
Unaffected: >= 1.3.8-r1
Architectures: 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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=media-gfx/graphite2-1.3.8-r1"
