CVE-2024-6387 details a flaw in OpenSSH that could *potentially* give an
attacker a root shell in "6-8 hours"
It's not in MITRE yet, but Qualys have named it "regreSSHion" and you can
read about it on their site
There's an updated package in Debian already, but it looks like the
information's still embargoed (even the openssh package changelog is
404ing) so I can only *assume* they've fixed it but can't tell anyone yet
(it wasn't on
security.debian.org just now either
This is probably an update you don't want to be sleeping on
