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"
