FreeBSD : GnuTLS -- flaw in DTLS protocol implementation (d887b3d9-7366-11ea-b81a-001cc0382b2f)

high Nessus Plugin ID 135110

Language:

New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

The GnuTLS project reports :

It was found that GnuTLS 3.6.3 introduced a regression in the DTLS protocol implementation. This caused the DTLS client to not contribute any randomness to the DTLS negotiation breaking the security guarantees of the DTLS protocol.

Solution

Update the affected package.
