Synopsis

========

 

POV-Ray includes a version of libpng that might allow for the execution

of arbitrary code when reading a specially crafted PNG file

 

Background

==========

 

POV-Ray is a well known open-source ray tracer.

 

Affected packages

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

 

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

Package / Vulnerable / Unaffected

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

1 media-gfx/povray < 3.6.1-r4 >= 3.6.1-r4

 

Description

===========

 

POV-Ray uses a statically linked copy of libpng to view and output PNG

files. The version shipped with POV-Ray is vulnerable to CVE-2008-3964,

CVE-2008-1382, CVE-2006-3334, CVE-2006-0481, CVE-2004-0768. A bug in

POV-Ray's build system caused it to load the old version when your

installed copy of libpng was >=media-libs/libpng-1.2.10.

 

Impact

======

 

An attacker could entice a user to load a specially crafted PNG file as

a texture, resulting in the execution of arbitrary code with the

permissions of the user running the application.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All POV-Ray users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=media-gfx/povray-3.6.1-r4"
