The vulnerability is caused due to an error within the "gnutls_session_get_data()" function (lib/gnutls_session.c) and can be exploited to cause a buffer overflow by tricking a client using the function into connecting to a malicious server. Note: Successful exploitation requires that the client calls the "gnutls_session_get_data()" function with an undersized buffer. SOLUTION: Update to version 2.12.4 or 3.0.7.
