Synopsis
========

Multiple vulnerabilities in Blender might result in the remote
execution of arbitrary code.

Background
==========

Blender is a 3D creation, animation and publishing program.

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

    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected
    -------------------------------------------------------------------
  1  media-gfx/blender      < 2.43-r2                       >= 2.43-r2

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

Stefan Cornelius (Secunia Research) reported a boundary error within
the imb_loadhdr() function in in the file
source/blender/imbuf/intern/radiance_hdr.c when processing RGBE images
(CVE-2008-1102). Multiple vulnerabilities involving insecure usage of
temporary files have also been reported (CVE-2008-1103).

Impact
======

A remote attacker could entice a user to open a specially crafted file
(.hdr or .blend), possibly resulting in the remote execution of
arbitrary code with the privileges of the user running the application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Blender users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-gfx/blender-2.43-r2"
