    <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.

  </description>
  <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 &quot;&gt;=media-gfx/blender-2.48a-r3&quot;</code>
  </resolution>
