It was discovered in gnutls before version 3.6.7 upstream that there is an uninitialized pointer access in gnutls versions 3.6.3 or later which can be triggered by certain post-handshake messages.

Weakness

The product does not initialize critical variables, which causes the execution environment to use unexpected values.
