NCSC advice

The National Cyber Security Centre (part of GCHQ) doesn't think that forcing regular password expiry is a good thing.

This two-year-old give-me-root hole is so trivial to exploit, you can fit it in a single tweet

Re: Thanks for making this public

The CVE was raised back in July

Raised doesn't mean made public.

I monitor CVEs for a living (it's tedious and boring: since early 2017 there has been a huge increase in ones of no relevance). The first I saw of it was this tweet, yesterday at 9:30 pm.

The NIST site says published on the 25th, too.

Theo de Raadt of OpenBSD is not happy

Nobody at OpenBSD was made aware of the bug until very late on, despite an OpenBSD developer being on the X security team. The release of 6.4 could have been delayed until after the public annoucement.

And spotteth twice they the camels before the third hour, and so, the Midianites went forth to Ram Gilead in Kadesh Bilgemath, by Shor Ethra Regalion, to the house of Gash-Bil-Bethuel-Bazda, he who brought the butter dish to Balshazar and the tent peg to the house of Rashomon, and there slew they the goats, yea, and placed they the bits in little pots. Here endeth the lesson.

libssh and libssh2

There are two similarly named projects:

libssh: the one with the vulnerability, and libssh2 which so far doesn't seem to be affected.

Red Hat / Centos, at least, use libssh2.

Note also that it only affects servers, not clients. sftp servers seem to be the most likely to be vulnerable and exposed.

Re: What about all the other diseases?

That makes as much sense as complaining that a blood test for ebola can't detect a sprained ankle.

I was referring only to diseases diagnosed by inspecting the retina. What's the point of an automated system when a specialist has to look at it anyway to diagnose other diseases?

As for the prosecution, sorry - I missed a sarcasm tag. As with the case of Dr Hadiza Bawa-Garba, the case should never have been brought in the first place.

Alan J. Wylie Silver badge

What about all the other diseases?

Macular degeneration, for one. And what happens if someone dies because of a missed diagnosis. Who do you prosecute then?

Re: What we need

Interested in your thoughts regarding Betamax v VHS

Video 2000

I contracted for a while at Pye TVT in Cambridge (working on a TV video effects console for the 1986 World Cup). Pye was a subsidiary of Philips, and there was a factory shop. Lots of employees, contractors and their friends and families ended up with Video 2000 recorders. Rumour had it that e.g. Dixons allocated the cassettes equally to all shops, and the manager of the Cambridge branch spent a lot of time on the phone talking to other branches to get their spare stock sent to him.

Getting back on topic, I also worked on the Acorn Archimedes and the Sinclair QL.

Dual use is hard.

Many years ago, I worked on computer aided mapping: semi-automated line following. Measuring the boundaries of all the woodland in the UK to calculate the total area, better 1:1250 maps with accurate buried utilities to stopping backhoes cutting fibre optic cables, what could possibly be wrong with that? Then came the Falklands war. Digitise the contours and produce a wire-frame perspective of Mount Tumbledown as viewed from Port Stanley, please.

A few years later, I worked on CNC blade tip grinders to make jet engines more fuel efficient. Making 747s greener is great. But what if the US Navy want some for their fighters? Or the Army for an AGT1500 turbine in an M1 Abrams tank?

Fibre break(s) near Manchester, too

Exa: At approximately 10:22am one of our core fibre links from London Telehouse to Manchester experienced total failure.

Bury is north of central Manchester, so these may be separate incidents.

CVE-2018-3693 "BCBS" Bounds Check Bypass Store"

Note that -3639 is a very similar "speculative store bypass" from May: don't get confused as I did for a short time. Could -3693 be the same as the Intel one?

Mark Rutland of ARM on the Linux Kernel Mailing List

arm64: spectre-v1 write fixes (CVE-2018-3693)

These patches inhibit spectre-v1-write gadgets found in arch/arm64, using the same mitigation applied to existing spectre-v1-read gadgets.

This issue is also known as CVE-2018-3693, or "bounds check bypass store". More details can be found in the Arm Cache Speculation Side-channels whitepaper, available from the Arm security updates site [1].
