How to not let the bad guys Segment Smack your Linux box around

There’s a new vulnerability du jour in Linux called Segment Smack. The early writeups about it were really confusing, so I sorted it out and wrote it up for my employer. You can read it here.

The key takeaways, in my opinion: You’re almost guaranteed to have to reboot for this to take effect. Also, most of the writeups say there’s nothing you can do to mitigate except patch. Not quite true. I show you in the writeup how to block the attack long enough to free resources so you can patch. There’s nothing good you can do, but there is a quick fix available to you if you need it.

An announcement regarding Facebook and this blog

Effective Aug 1, I won’t be able to post updates from the blog to my Facebook profile automatically. So if you follow me on Facebook, you won’t see blog posts after Aug 1. I have set up a Facebook page where I will be able to continue to post updates. If you’re interested in following this blog on Facebook, follow this page instead of me. If you want to watch me rant with my journalism school classmates from the 1990s, follow me.

And now I have two days to get posting to that page working. Wish me luck.
