Greenbone OS 21.04.11 released

For GOS 21.04, a new patch level is available.

With this release the Diffie-Hellman Ephemeral (DHE) key exchange algorithms were disabled for the default settings of the nginx web server and in all cases for the SSH service as they are vulnerable to CVE-2002-20001.

Several bugs were fixed. Among others, a major bug where running scans were either stopped or interrupted when changing the HTTPS timeout setting via the GOS administration menu. Additionally, an error was fixed where HTTPS certificates using Elliptic Curve Cryptography (ECC) were detected as using RSA cryptography.

In total, GOS 21.04.11 covers 6 improvements and 10 bug fixes.
