+  <title>Ruby: Terminal Control Character Injection</title>
+  <synopsis>
+    An input sanitation flaw in the WEBrick HTTP server included in Ruby might
+    allow remote attackers to inject arbitrary control characters into terminal
+    sessions.

+  <background>
+    <p>
+    Ruby is an interpreted scripting language for quick and easy
+    object-oriented programming. It comes bundled with a HTTP server
+    ("WEBrick").
+    </p>
+  </background>
+  <description>
+    <p>
+    Giovanni Pellerano, Alessandro Tanasi and Francesco Ongaro reported
+    that WEBrick does not filter terminal control characters, for instance
+    when handling HTTP logs.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A remote attacker could send a specially crafted HTTP request to a
+    WEBrick server to inject arbitrary terminal control characters,
+    possibly resulting in the execution of arbitrary commands, data loss,
+    or other unspecified impact. This could also be used to facilitate
+    other attacks.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Ruby 1.8.7 users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=dev-lang/ruby-1.8.7_p249"</code>
+    <p>
+    All Ruby 1.8.6 users should upgrade to the latest version:

+    # emerge --ask --oneshot --verbose "&gt;=dev-lang/ruby-1.8.6_p388"</code>
