Greenbone OS 5.0.3, 4.3.14 and 4.2.29 released

For GOS 5.0, 4.3 and 4.2 a new patch level is available:

Each patch level contains a security update for the Linux kernel, addressing the “SACK Panic” vulnerabilities which allow remote denial of service attacks against the TCP stack, affecting most Linux systems worldwide.

We strongly recommend to upgrade all GOS setups.

The Greenbone Security Feed has been updated with local security checks for Debian to detect the vulnerabilities in question. Checks for other Linux distributions will be available soon.

In total each of the patch levels covers 1 improvement.
