<description>
<p>
Steffen Joeris reported that Blender's BPY_interface calls
PySys_SetArgv() in such a way that Python prepends sys.path with an
empty string.

<impact type="normal">
<p>
A local attacker could entice a user to run "blender" from a directory
containing a specially crafted Python module, resulting in the
execution of arbitrary code with the privileges of the user running the
application.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Blender users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/blender-2.48a-r3"</code>
</resolution>
