+
+     <para>
+      A modified server, or an unauthenticated man-in-the-middle, can
+      send a not-zero-terminated error message during setup of GSSAPI
+      (Kerberos) transport encryption.  <application>libpq</application>
+      will then copy that string, as well as following bytes in
+      application memory up to the next zero byte, to its error report.
+      Depending on what the calling application does with the error
+      report, this could result in disclosure of application memory
+      contents.  There is also a small probability of a crash due to
+      reading beyond the end of memory.  Fix by properly zero-terminating
+      the server message.
