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:
