Thanks for posting. Saw this headline, but didn't get to actually read the article yet.

Looks like that vulnerability is worse than expected.

Multiple vulnerabilities patched this month. Make sure you're account is paid up so you can keep everything updated. Or more reasonably toss the gear for something reasonably priced.

At least 1 remote vulnerability, again.
