Synopsis
========

A vulnerability in FreeType could result in execution of arbitrary code
or Denial of Service.

Background
==========

FreeType is a high-quality and portable font engine.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  media-libs/freetype         < 2.5.3-r1               >= 2.5.3-r1 

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

A stack-based buffer overflow exists in Freetype's cf2_hintmap_build
function in cff/cf2hints.c.

Impact
======

A remote attacker may be able to execute arbitrary code or cause a
Denial of Service condition via specially crafted font file.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All FreeType users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-libs/freetype-2.5.3-r1"

Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying these packages.
