+  <title>Ruby: CGI::Session creates files insecurely</title>
+  <synopsis>
+    When used for CGI scripting, Ruby creates session files in /tmp with the
+    permissions of the default umask. Depending on that umask, local users may
+    be able to read sensitive data stored in session files.

+    Ruby is an Object Oriented, interpreted scripting language used for many
+    system scripting tasks. It can also be used for CGI web applications.

+    <p>
+    The CGI::Session::FileStore implementation (and presumably
+    CGI::Session::PStore), which allow data associated with a particular
+    Session instance to be written to a file, writes to a file in /tmp with no
+    regard for secure permissions. As a result, the file is left with whatever
+    the default umask permissions are, which commonly would allow other local
+    users to read the data from that session file.

+  <impact type="normal">
+    <p>
+    Depending on the default umask, any data stored using these methods could
+    be read by other users on the system.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    By changing the default umask on the system to not permit read access to
+    other users (e.g. 0700), one can prevent these files from being readable by
+    other users.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Ruby users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge sync
+
+    # emerge -pv ">=dev-lang/ruby-your_version"
+    # emerge ">=dev-lang/ruby-your_version"</code>
