Synopsis

========

 

Multiple integer overflows in FreeType might allow for the remote

execution of arbitrary code or a Denial of Service.

 

Background

==========

 

FreeType is a high-quality and portable font engine.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 media-libs/freetype < 2.3.9-r1 >= 2.3.9-r1

 

Description

===========

 

Tavis Ormandy reported multiple integer overflows in the

cff_charset_compute_cids() function in cff/cffload.c, sfnt/tccmap.c and

the ft_smooth_render_generic() function in smooth/ftsmooth.c, possibly

leading to heap or stack-based buffer overflows.

 

Impact

======

 

A remote attacker could entice a user or automated system to open a

specially crafted font file, possibly resulting in the execution of

arbitrary code with the privileges of the user running the application,

or a Denial of Service.

 

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-2.3.9-r1"
