+    Multiple vulnerabilities might allow for the execution of arbitrary code in

+    GnuTLS is an implementation of Secure Sockets Layer (SSL) 3.0 and
+    Transport Layer Security (TLS) 1.0, 1.1 and 1.2.

+    <p>
+    Ossi Herrala and Jukka Taimisto of Codenomicon reported three
+    vulnerabilities in libgnutls of GnuTLS:
+    </p>
+    <ul>
+    <li>
+    "Client Hello" messages containing an invalid server name can lead to a
+    buffer overflow when evaluating "Security Parameters" (CVE-2008-1948).
+    </li>
+    <li>
+    Multiple "Client Hello" messages can lead to a NULL pointer dereference
+    (CVE-2008-1949).
+    </li>
+    <li>
+    A TLS handshake including an encrypted "Client Hello" message and an
+    invalid record length could lead to a buffer overread (CVE-2008-1950).
+    </li>
+    </ul>
+  </description>
+  <impact type="high">
+    <p>
+    Unauthenticated remote attackers could exploit these vulnerabilities to
+    cause Denial of Service conditions in daemons using GnuTLS. The first
+    vulnerability (CVE-2008-1948) might allow for the execution of
+    arbitrary code with the privileges of the daemon handling incoming TLS
+    connections.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All GnuTLS users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=net-libs/gnutls-2.2.5&quot;</code>
