The remote host is missing an update to blender announced via advisory USN-699-1.
Details follow:
It was discovered that Blender did not correctly handle certain malformed Radiance RGBE images. If a user were tricked into opening a .blend file containing a specially crafted Radiance RGBE image, an attacker could execute arbitrary code with the user's privileges. (CVE-2008-1102)
It was discovered that Blender did not properly sanitize the Python search path. A local attacker could execute arbitrary code by inserting a specially crafted Python file in the Blender working directory. (CVE-2008-4863)
Solution: The problem can be corrected by upgrading your system to the following package versions:
Ubuntu 6.06 LTS: blender 2.41-1ubuntu4.1
After a standard system upgrade you need to restart Blender to effect the necessary changes.
