But we’ll also look at a key issue revealed by the double listing: if security experts can so easily lose sight of an existing vulnerability to the extent that a vulnerability is relisted as “new” and “just discovered” – what does it say about the state of vulnerability management?

And what does it mean for Linux users around the globe, vulnerable to countless offensive strategies – but dependent on the security experts for assistance?
