+*** [GNUTLS-SA-2008-1-1]
+*** libgnutls: Fix crash when sending invalid server name.
+The crash can be triggered remotely before authentication, which can
+lead to a Daniel of Service attack to disable the server. The bug
+cause gnutls to store more session resumption data than what was
+allocated for, thus overwriting unallocated memory.

+*** [GNUTLS-SA-2008-1-3]
+*** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
+The crash can be triggered remotely before authentication, which can
