+  <title>GnuTLS: RSA Signature Forgery</title>
+  <synopsis>
+    GnuTLS fails to handle excess data which could allow an attacker to forge a

+    verify.c fails to properly handle excess data in
+    digestAlgorithm.parameters field while generating a hash when using an
+    RSA key with exponent 3. RSA keys that use exponent 3 are commonplace.

+  <impact type="normal">
+    <p>
+    Remote attackers could forge PKCS #1 v1.5 signatures that are signed
+    with an RSA key, preventing GnuTLS from correctly verifying X.509 and
+    other certificates that use PKCS.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All GnuTLS users should update both packages:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --update --ask --verbose "&gt;=net-libs/gnutls-1.4.4"</code>
