Title:	Blender: User-assisted remote execution of arbitrary code
Date:	04/23/2007
Bugs:	#168907
ID:	200704-19

Synopsis

A vulnerability has been discovered in Blender allowing for user-assisted arbitrary code execution.

Background

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

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-gfx/blender	< 2.43	>= 2.43	All supported architectures

Description

Stefan Cornelius of Secunia Research discovered an insecure use of the "eval()" function in kmz_ImportWithMesh.py.

Impact

A remote attacker could entice a user to open a specially crafted Blender file (.kmz or .kml), resulting in the execution of arbitrary Python code with the privileges of the user running Blender.

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"
