Re: arm -> low power. POWER -> ?

"What does ibm bring to the table in this that would interest anyone over x86/x64?"

Oh, maybe an established 64-bit system (compared to ARM) with a better underlying architecture (compared to x86) and willingness to license at affordable costs?

Yes, Intel has the lead in process technology, and yes the legacy software market for x86 is very important and deeply ingrained, but there is a lot of new stuff that has no such constraint.

Re: ACLs & OS willy-waving

I thought I might as well come out from under my bridge to weigh in on this:

In the beginning there was no Windows security at all, and BillyG said Lo! Make it so we don't suck! Thus Dave Cutler was employed to design a worthy OS and, being who he is, it had to be non-UNIX in every aspect, presumably due to some nasty experience at the hands of some UNIX admins at a student party or similar.

Thus he created NT, and we saw it was good and multi-platform. Anything and everything had an ACL for security and computer scientists around the world marvelled at how complex one could create a machines permissions. Alas, it did not last because those in MS' demonic marketing department decided that it had to be compatible with some legacy stuff based upon the old singer-user non-networked model of security, and speed was poor and thus the video subsystem, and other stuff, was thrust into the ring 0 code that once was pure kernel. Then it became x86 only, until very recently when the bastard child WinRT was created.

And darkness descended upon the windows ecosystem as software was allowed free reign by default to do things it should not, and the tenderest parts of the user's nether regions became the favourite lunch of malware writers the world over.

Meanwhile the old UNIX/Linux model chugged along on the bases of multi-user systems with a crude, but effective, set of permissions that were enforced by default leading to far less trouble.

And so children, the lesson here is analogous to the tortoise and the hare: Windows should have been the pinnacle of security, but was let down by pesky users not knowing or caring how to use ACLs, and by time it became a problem so much legacy software was doing it all wrong. Given you need to use a tool to simply find out what ACLs are in use, it is hardly surprising.

Linux is indeed less sophisticated by default, but as its basic segregation of admin & user has always been enforced, software for it always played well that way, thus basic security has always "just worked".

For ACLs on Linux you can copy this way:

getfacl file1 | setfacl --set-file=- file2

And yes, ACLs on Linux are not completely consistent across different file systems, but how consistent is Windows ACLs across file systems? Oh yes, it is only NTFS...

Re: @Jamie Jones

Thanks for the feedback, I stand corrected.

"If you follow the spaghetti trail that is the source code"

I think you have identified a significant problem just there.

"I.e. it's read-overflow (or 'buffer overflow' by reading rather than writing) - nothing to do with the memory allocation!"

If they are really using a stack-based source then electric fence would not have caught it, but I would have hoped some of the code profiling tools would have thrown up a warning about the copy size being potentially bigger than the buffer.

Re: @Michael Wojcik

I'm not sure, but usually if you overrun a buffer then standard tools like the "electric fence" library or the valgrind tool fill find the problem.

Of course, if you write obscure code and use a not-very-well-thought-through alternative version of malloc() then things might not go so well...

Re: leaving vulnerable information in memory in the first place?

"You using calloc doesn't solve a damn thing."

Except in this bug it would have, as the padding beyond the heartbeat request that was returned when the request length was longer would always be zero'd. Thus no leaks.

Where you are correct is that it won't stop other heap-walking mischief where something else gets hold of a freed block with sensitive data. Though others using calloc() by default would minimise that risk as well.

What would be nice would be a built-in cfree() equivalent that would clean up by already knowing the allocated buffer size to zero it, so that you could use "#define free(x) cfree(x)" (or some compile flag) to apply generically without having to re-write code to pass the size as well.

Re: leaving vulnerable information in memory in the first place?

ALL computers leave essential information in memory - they need to in order to work!

The issue here, as is so often the case, is poor use of malloc()/free() and the opportunity for such memory to be re-used without sanitisation.

I'm not an expert, but I use calloc() in all but uber-time-critical steps partly to stop this sort of thing, and partly so when I do make a boo-boo at least I get consistent borking as it always starts with zero'd memory before I go on to abuse it.

The patch is about keeping the keys in memory that is not easily re-used, which is good, but as already reported the OpenSSL project really needs some proper support and a bit more code review. Hey NSA/GCHQ could you do something useful for us for a change?

Re: AntiCopy AACS

That was my first thought, as how many Blue Ray players have DAC and analogue electronics that is even a match for studio quality 16-bit/CD style hardware, let alone enough to show differences (if any) in the standards?

Oh yes, these disks will sound *different* but that is down to "re-mixing" for effect, not because you get a fundamentally better product.

As others have pointed out FLAC is already better than CD (higher quality possible with less storage) and no DRM - what is there not to like?

US taxman blows Win XP deadline, must now spend millions on custom support

Paul Crawford

Re: @LDS

In most cases the XP machines that can't be economically replaced are so because of one or two specific jobs, and very rarely will that need much, if any, internet access. So a firewall that simply white-lists the things it needs (e.g. NTP and specific IP addresses it needs) will stop most things.

If you can't access web/email on a given machine then it won't get drive-by attacks and also no casual use. If it can't talk to most of the internal machines then such attacks won't spread.

And of course you have disable auto-run on all devices, if not mass storage completely, to stop USB attack vectors on every machine?

Driver drama delays deep desert XP upgrade

Re: Hand back the geek ID card, return the butter knife and leave

When faced with a sick Windows box, my steps are:

1) Open it and hoover out dust & crap, then check for Bulging Capacitors Of Death on the motherboard.

2) Boot a Linux CD/USB (old PCs often wont boot from USB happily so CD/DVD needed) and run the memory tester.

3) Check the HDD SMART status to see if its dying.

4) Boot a BitDefender or Kaspersky "rescue CD" and check for root kits and lesser malware.

If all of the above pass, then you know its 'just' a simple problem. But for most PCs not looked after by a competent Windows admin, you know its going to have so much crap installed and partly uninstalled that saving the data and nuking from orbit is the best solution.

That is, assuming they have the original Windows disk / rescue disk they were told to make when the PC was new...

Re: @LDS

The "backward compatiblity of Linux" problem is when you change kernel version and some muppet decided, yet again, to change APIs on the basis that they assume all can just re-compile.

What I said was you can patch a working system for security holes in virtually every case without changing versions. I did not say it was easy, but possible. With MS you have no such ability at all, and given the typical extended support costs they are asking for you could hire a decent programmer just for that job alone.

Re: Paul Crawford

The MC6800 series is a CPU, not a computer platform, i.e. not a standardised board with "computer" (CPU, RAM, boot loader, etc) and expansion slots for extra interfaces & custom cards.

Most equipment designers want to concentrate on the "added value" they provide, which is the custom part, and not to have to develop the computer/boot loader/networking/etc.

That was why the original IBM-AT was so attractive - you got a functioning stand-along computer, along with plenty of development tools, and documented hardware that made it easy to build a special ISA card for whatever custom job you needed done.

The transition to Windows made that harder but safer (Linux is marginally easier as you can see most device driver's code to copy & adapt, but neither as simple nor dangerous as DOS' direct-to-hardware approach), and PCI is far more complex to implement (even with a cots chip or IP core), but the same basics apply: a PC is still a cheap, easy and longest lasting platform to develop for compared to any other I can think of.

Re:@Decade

You are right that Windows was a bad choice of platform for so many reasons, but usually the decision is based on what is cheap & practical now, with the presumption that product development and support will continue so upgrades to newer hardware/OS are thus managed.

In practice companies fail, get bought over, or otherwise decide to orphan products so support stops but lots of users have business-critical stuff that is no longer upgradable when the OS, like Windows, drops aspects of backwards-compatibility (often for other good reasons, like security).

Sadly short of an open source system, you are stuck making the best of what you have, not what you wanted.

More recent MS OS with product activation checks are even worse and should never be used. But they will, because some green programmer only knows that way and all problems look like nails...

But retuning to one of your gripes, that of PC hardware, what other computer platform has been more-or-less supported for 20 years? It is far from ideal, but a longer supported choice is hard to find.

Re: So does OSX and Linux...

Not as such, but with Linux you have the code and the patches and if it matters enough find someone who can patch things and also there is an incentive to share that.

In most cases it is stuff that MS has dropped that makes upgrading a pain, along with DRM-like stuff that rejects old drivers that are not signed, etc.

But really for most XP-dependants the road now is likely to be one of auditing what they do, why, and how to isolate them from t'Internet and then moving all web/email/exposed stuff to newer, more secure, machines.

In most cases, probably special hardware aside, if you have XP-specific software the best solution is to run an XP VM in another host OS (my choice Linux, but Win7/8 just as effective).

You get 100% XP compatibility, no future hardware driver issues, the ability to restrict internet access to the (soon very vulnerable) XP VM, and a host computer that runs whatever new stuff you need fairly safely.

Re: Lifetime free support?

If I was being aggressive I would say "because they sold it with so many bugs in the first place".

If I was being helpful I would have suggested to MS that they could have offered support for, say, $5 per user per year after the first year. That is pretty small per user, but a tidy sum with some hundreds of millions of users and you could get support as long as you want, and they can afford to pay the staff to do so.

But doing what the customer wants seems to be an alien concept to so many companies.

@jason 7

"Try using a 13 year old install of XP on a 13 year old PC and you'll find that it doesn't work...very well at all."

It works fine if you have the original configuration - and typically that means no AV and anti-spyware running, and not piles of software that no one really uses but each one starts its own updater on boot-up. If not running well, usually some RAM as an upgrade is enough to restore sanity cheaply.

However, I think you will find there are two classes of hold-outs where the machine is newer but they stick with XP:

(1) Folk without the income or desire to spend on a PC, the old "it works fine for me and I hardly use it anyway" brigade. Definitely not El Reg readers.

(2) Folk who have the budget and support, but are sticking with XP because something they have won't run acceptably on a newer OS. Now you could argue they should simply upgrade the program(s) they use to avoid this, but there could be a whole range of reasons why not:

2.1) Stupidly expensive to do as it was custom software, etc. (thinking here of gov and IE6 lock-in, for example).

2.2) Not possible as no newer software exists (e.g. for old hardware, or company went bust, etc)

2.3) The upgrades change things in ways that will (or could possibly) break something key to their business (e.g. industrial control where it took a lot of time & money to certify the system in the first place).

All can be sorted with enough money, but it is likely to be WAY more than the cost of a new PC/OS.
