Synopsis
========

A vulnerability has been discovered in FreeType, which can lead to
remote code execution.

Background
==========

FreeType is a high-quality and portable font engine.

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

Package              Vulnerable    Unaffected
-------------------  ------------  ------------
media-libs/freetype  < 2.13.1      >= 2.13.1

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

Multiple vulnerabilities have been discovered in FreeType. Please review
the CVE identifiers referenced below for details.

Impact
======

An out of bounds write exists in FreeType when attempting to parse font
subglyph structures related to TrueType GX and variable font files. The
vulnerable code assigns a signed short value to an unsigned long and
then adds a static value causing it to wrap around and allocate too
small of a heap buffer. The code then writes up to 6 signed long
integers out of bounds relative to this buffer. This may result in
arbitrary code execution. This vulnerability may have been exploited in
the wild.

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-2.13.1"
