Synopsis
========

A buffer overflow in FreeType might allow remote attacker(s) to execute arbitrary code.

Background
==========

FreeType is a high-quality and portable font engine.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/freetype < 2.10.3-r1 >= 2.10.3-r1

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

A flaw in FreeType's handling of embedded PNG bitmaps was discovered
where the image height and width was not checked to be within bounds.

Impact
======

A remote attacker could entice a user to open a specially crafted font
file using FreeType possibly resulting in the 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 FreeType users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/freetype-2.10.3-r1"
