Описание
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.
A flaw was found in the way gnutls handled malformed TLS 1.3 asynchronous messages. An attacker could use this flaw to crash an application compiled with gnutls via invalid pointer access.
