<background>
<p>
Ruby is an interpreted scripting language for quick and easy
object-oriented programming. Ruby supports the safe execution of
untrusted code using a safe level and taint flag mechanism.
</p>

<p>
Dr. Yutaka Oiwa discovered that Ruby fails to properly enforce
safe level protections.
</p>
</description>
<impact type="normal">
<p>

code beyond the restrictions specified in each safe level.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
