Severity ?

6.5 (Medium) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H

Details

A NULL pointer dereference flaw was found in the GnuTLS software in _gnutls_figure_common_ciphersuite(). When it reads certain settings from a template file, it can allow an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial of service (DoS) that could crash the system.
