  <title>Ruby: Security bypass vulnerability</title>
  <synopsis>
    Ruby is vulnerable to a security bypass of the safe level mechanism.
  </synopsis>
  <product type="ebuild">ruby</product>
  <announced>October 06, 2005</announced>
  <revised>October 06, 2005: 01</revised>
  <bug>106996</bug>
  <access>remote</access>
  <affected>
    <package name="dev-lang/ruby" auto="yes" arch="*">
      <unaffected range="ge">1.8.3</unaffected>
      <vulnerable range="lt">1.8.3</vulnerable>
    </package>
  </affected>
  <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>
  </background>
  <description>
    <p>
    Dr. Yutaka Oiwa discovered that Ruby fails to properly enforce
    safe level protections.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could exploit this vulnerability to execute arbitrary
    code beyond the restrictions specified in each safe level.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Ruby users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-lang/ruby-1.8.3&quot;</code>
  </resolution>
