Secunia Research has discovered a vulnerability in Blender, which
can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to the insecure use of the "eval()"

arbitrary Python commands by tricking a user into importing a
specially crafted "*.kml" or "*.kmz" file.
