Heads up: Debian's package manager is APT for root-level malware injection... Fix out now to thwart MITM hijacks

Re: "Supporting HTTP is fine,"

Oh.... just read the original problem report... It's NOT tampering with the checksums, it's bypassing them, because (A) the inter-process channel (between apt-aquire and apt) quotes some progress stuff literally from the HTTP communication. and (B) the signature file can include pre-signature junk. e.g. an entire .deb!

Thanks to the extra junk in the channel, the master process gets fed the wrong signatures and dpkg gets told to install the signature file not the verified package, and I guess it ignores the trailing signature.

So it's really an out-of-band data / injection attack that sneaks in an extra payload after the cryptographic checks have passed, and it basically means that someone controlling a mirror can inject anything she likes to her users.

To my mind the roles of master/worker roles probably need rethinking, so that the type of filename replacement used here and such-like aren't possible in future versions, not to mention that the downloader shouldn't be responsible for only half of the security checks.

nagyeger

Re: "Supporting HTTP is fine,"

Yes, they are, but the checksums are equally unsafe, because ... they're downloaded via HTTP :)

But the checksums are in files which are themselves digitally signed, aren't they? That's why you can't just start using any old repo, but need to tell GPG about the repository signing key too.

And the public key arrives over https, from a keyserver.

Are they saying that despite requiring a key they're not using it properly? I don't understand...

Core blimey... When is an AMD CPU core not a CPU core? It's now up to a jury of 12 to decide

nagyeger

Re: Another frivolous lawsuit

I thought hyperthreading was basically a set of alternative registers for the same hardware?

My definition of core is probably wrong, but I'd have thought a core was defined by a patch of silicon that would continually (barring interrupts) burn cycles given "NOOP; JMP -1" and had a its own set of general purpose registers.

Hyperthreading fails at "continually" bit. it's just clever time-sharing. branch prediction units, etc. don't have a complete set of their own registers (unless I'm wrong), so they're not cores either. On-chip caches, FPU, prefetch and all the rest of the fluff that keep the bits flowing and feed spectre/meltdown so well cannot be part of the definition of a CPU core, otherwise you're saying that a 6502 / Z80 / 286 / atmega-328p don't have a core.

I'm looking forward to the time when owning bitcoin is taken as strong evidence of operating some kind of bot-net, selling something illegal or dining on the blood of polar bear cubs (or other global-warming victim), and thus the value in several sectors of society is negative.

Just imagine...

Just imagine that inside your box there were 2 devices. One which you trusted and only ran code that you'd actually installed yourself, and anything that ran anything else (e.g. Javascript) ran on "untrusted" hardware. Then you'd need need to have a way of communicating safely between the two, with some user interface devices and the ability to send data from one to the other, and a fast bus/network between the two. And some machines would have all the oomph in the trusted box and others in the untrusted box for games and stuff, and there'd be a hardware video multiplexer doing it's clever stuff, like an updated version of what we had back in the days of video overlay cards on VGA, so that you don't need to try shoving 120fps video down the network pipe.

Then high spec machines would include extra separate modules hanging off the bus/network so that eg. game engines didn't interfere with google docs.

And there'd be a some kind of manager thingy on the main computer to make sure that let you interact with the different untrusted-compute devices while maintaining isolation. Actually, maybe the display/HID ought to be a separate device, maybe with a really simple RO filesystem, and everything work via that main UI box too. ...

Oh. prior art, my UI box has just basically become an X server hasn't it?

kid control / smut filtering

As a parent of teenagers and youger, it's quite handy knowing that my kids are not going to be able to do some involuntary bitcoin mining for nasty.smut.site without going to extreme measures, nor stumble on disturbing rubbish. Blocking DNS except via trusted (blacklisting) servers does that for me, has done that for me, and I hope will keep doing that for me.

Except that firefox has now published a 4 step process to break that entire model.

Given that practically everything uses SNI and so sends the destination host out as plain text these days, the 'poor guy in china' security red-herring is just that, unless he's also using a VPN. In which case, why are we having this conversation?

To my mind this is at least 95% about ensuring that the smut industry can deliver their filth. I really cannot see any other party that benefits from it.

It should but they don't, not even round here where power cuts are commonplace.

FYI, there are loads of CCTV type sealed lead-acid battery-backed up 12v power supplies out there, some of which are complete with a nice box and low voltage cut-out to stop you under-voltaging the cells. Cost is around 30quid. Add a low-drop 12v regulator (or a step-down DC-DC converter if you need 5v) just in case your ISP's box doesn't want 14v with ripple, and Bob is the brother of one of your parents, as they say.

I now get at least 8 hours's internet/phone compared to around 1 hour if the thing was going up to mains freq and back to 12v again.

Re: Be much more interested in...

You forgot:

In Europe, the half-hearted attempt at safety shutters on Schuko/french sockets relies upon the pins pushing sloping shutters out of the way, a motion which is only made possible by the presence of some kind of lubricant. When said lubricant has melted/vanished/gone sticky or when the track/pivot on which the shutters are laughingly described as moving is no longer in perfect condition, the only way to get the pins into the socket remaining is wiggle, twist and apply extreme force, e.g. with a large hammer. Said tool of course further damages the shutters and does bad things to the cable, and the whole process may lead to bruising of the head against nearby brick walls.

Add to this the disaster known as "switched socket, what's that?" and you have to unplug / plug in the stupid things far more than you would in the UK.

data rate

Whats the baud rate for a tin cup and and a piece of string?

If you can get hold of some light, inextensible string, as beloved by high-school physics teachers, then your signals arrive instantaneously (0 propagation delay, since the string will not extend) and depending on the mass of your cup then your data rate could exceed that of all known network cables.
