Staff sacked after security sees 'suspect surfer' script of shame

Re: Access Denied

My experience in the late '90s was that you had to be very careful about blocking on keywords in domains. https://www.essex.ac.uk/ anyone? (Yes - a genuine example that I came across).

Many years ago, we had an ISDN connection at the office, and a bank of modems. HTTP connections were forced to go through a Squid proxy. I had a similar little script which grepped the log for "interesting" keywords, but not much interest was shown in this from above.

However, one day all our sales people and managers were gathered together at a hotel for a big meeting. One of my colleagues in network admin was due to address them, and took the opportunity to remind them that, as in the T's and C's they had acknowledged, our network was monitored for inappropriate (and expensive: on-demand ISDN had a per-call cost) usage. There were no sackings as a result, just a few red faces as he stood at the lectern and read out a few of the less unsafe-for-work domains that had been visited the previous night.

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.

Theological AI, what could possibly go wrong?

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.

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?

Who would have thought, 35 years ago, that all the work that a Ph.D. student from Oxford, my colleagues and I were doing programming a Laser-Scan Fastrak in Fortran on a VAX 11/780 to recognize the junctions on Ordnance Survey 1:1250 maps would lead to this?

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?

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].
