Openness only allows privilege escalation, not remote code execution. This vulnerability can be exploited by attackers who aim to compromise Linux systems and manage to gain access. For example, brute force attacks.

You can fix the problem by updating your system to the latest package versions. Vendor supported patched versions were provided by Ubuntu, RedHat, Debian, Fedora, Gentoo, and others.
