Slashback: Highness, Hominess, Hole-ines

Posted by timothy on Tue Dec 04, 2001 06:59 PM
from the family-locus-shifting-south dept.
Slashback tonight with updates on SSH vulnerabilities, the Queen's web server, the European answer to GPS (in danger, it seems) and your ever-thinner rights to use software for anything you don't have specific permission for.

Sometimes being British means self-flagellation. Ferox writes: "The November Web Site Survey from Netcraft reveals something interesting: 'Two years ago the Queen of England became an unlikely icon for the Linux revolution when her webmaster replaced Solaris as the platform for the Royal Family's site, citing the better price/performance of the Dell/Linux platform over the previous incumbent, Sun/Solaris. The open source community celebrated and speculated on when the Apache web server might receive the "By Royal Appointment" moniker. This week the site has changed platforms again, this time to Microsoft-IIS.'"

Keep your hands and passwords inside the car at all times. Niels Provos passed along word of his ongoing research into network security, with some slightly depressing news about the state of Internet security.

Even though the CRC32 bug has been found over a year ago, over 30% of all servers are still vulnerable today. Graph at http://www.citi.umich.edu/u/provos/ssh/crc32.png.

In February 2001, Razor Bindview released their "Remote vulnerability in SSH daemon crc32 compensation attack detector" advisory, which outlined a gaping hole in deployed SSH servers that can lead to a remote attacker gaining privileged access.

In November 2001, Dave Dittrich published a detailed analysis of the "CRC32 compensation attack detector exploit." This exploit is currently widely in use. CERT released Incident Note IN-2001-12.

At the Center for Information Technology Integration, Niels Provos and Peter Honeyman have been scanning the University of Michigan for vulnerable SSH server software to identify and update vulnerable SSH servers. However, scans of the Internet show that system and security administrators must react and update their SSH servers. At this writing, over 30% of all SSH servers appear to have the CRC32 bug.

A simple solution is to remove support for Version One of the SSH protocol. The majority of servers on the Internet support the SSH v2 protocol. To test whether your network has vulnerable SSH servers, you might use the ScanSSH tool.

Don't play with your food, or your games. janolder writes "In the matter of the Civilization III translation project (articles on slashdot, apolyton and heise), the fans have gotten the short end of the stick. The project web site (translation.civ3.de) has been down for a while. Earlier this week, both the web site operator and Kai Fiebach, the project leader, signed Infogrames' cease and desists out of fear of further legal action. The legal position (not to mention the moral postion) of the fans did not appear to be too weak - EULA's are not binding in Germany and supplying patches to a program is certainly not the same as translating a book and distributing the translated manuscript.

Infogrames Germany has issued another press release (translation and my comments) justifying their legal action and position. It makes for an interesting peek into the mindset of a game publisher.

The good news is that Infogrames is considering a more timely release of Civilzation III in Germany.

The bad news is that the cease and desists apparently forbid any modification of Civ3 in any way, shape or form. So no more custom maps for your friends, custom rules or any such copyright infringing activity, please! Is it just me, or has the world suddenly become a less interesting place?"

Not as if Americans always know where we are, either. ByTor-2112 writes "Hate to be the bearer of bad news so soon after a story is posted, but as I commented on the previous story, it appears that galileo has some funding issues. Honestly, did anyone really expect the EU to go through with it? It took them long enough to agree on a common currency!"

    I disagree with the argument that translating and distribution Civ 3 is not the same as translating and distributing Harry Potter. A better analogy would be the translation and distribution of only the first chapter of Harry Potter: It would not be the complete work and it may stimulate sales, but it's still a copyright violation (hence the "in whole or in part" bit in licenses).

      Thats seems to me to be closer to distributing a demo of some sort. And definately a copyright violation.

      I think an even better analogy would be distributing free glare-reducing transparencies to lay over the pages and reduce eye strain and a free bookmark to help enjoy your purchase. If patches are being distributed that require the game already be installed, there should be no problem (IMHO). But the entire game with reworked languages should not be distibuted, as that would imply that every user already PAID for the game and thats just not reasonable.

      Except that this seems to be providing a patch, not the entirety of the translated work. In which case, only those who have purchased the full version will have the translation. Without the original work, the patch is just a useless file.

      So, an even better analogy would be a reading translator that would read the Harry Potter book to you in German. Copyright violation? No. Fair use? Definitely.

      • a reading translator that would read the Harry Potter book to you in German. Copyright violation? No. Fair use? Definitely.
        A very good analogy. If we push it a little further, we see what's wrong your your other assertions.

        Suppose Voldemort Publications sells you an PDF of Black Magic for Beginners on CD. The text is copyrighted, but that's not enough for VP. So they make you accept a license agreement that specifies that you can only read the book directly off the CD and you may not manipulate the text in any way.

        You pop the CD in your computer and discover that the text is in Ancient Etruscan. When you call up to complain, they explain that the English translation is licensed to Massively Manipulative Monopolies. No they don't know when it will come out.

        No problem. You go to the Hogwarts web site and download a translation spell. But as soon as you begin to incant Logos Anglicia! a VP legal troll appears in a puff of yellow-green smoke. He accuses you of violating the no-manipulation clause in your license agreement. You try to tell him that such a clause is unenforceable, but he just shrugs and says, "We think it will stand up in court. You're welcome to consult your own lawyer, of course."

        "This is ridiculous!" you say. "I acquired the book legitimately, and I have a right to read it."

        "Well, we have a right to maximize our return on our investment. That's why MMM is handling the English version -- they're much better at marketing to muggles than we are. Now cut it out. This agreement is enforcable in the Court of Giant Warts!"

    • No, I don't think that's a good analogy. A chapter is a specific section of a book; it is just as usable as if one were to have the book and read only that chapter. Your analogy would be like releasing a fully-playble version of Doom, but limited to the first level only. (which is pretty close to what happened, but not the point...)

      A better analogy would be to offer a list of new character names and objects and where in the book these names should be inserted. The purpose, of course, would be to localize the book: the book could be cajunized-- Jonny Pottieu would be chompin' on crawfish at a charivari [charivaricajunband.com], instead of whatever harry potter ate...

      There is no copyright violation... you are replacing the text from the original program, and not distributing any byte that was in the original. The user must own the original to apply the patches to; otherwise the patches are useless.
    • I disagree with the argument that translating and distribution Civ 3 is not the same as translating and distributing Harry Potter.

      Translating and distributing Civ3 is exactly what didn't happen. The translation team created new text lookup files and offered them as a patch for the US version of Civ3.

      Had they instead offered a complete localized package for download, I'd have to agree with you. As it is, Infogrames have really ruined their reputation in this market.

    • I disagree.

      The difference between Harry Potter and a computer game is simply that with Harry Potter, the text is the product. Period. Whether that text is read on a computer screen, off of a sheet of paper or off of microfilm, the text is the product that is being sold.

      In the case of a computer game, the product is the game, which includes the text, the gameplay, the graphics, music, sound effects, what-have-you.

      In the case of someone "ripping off" Harry Potter, the "ripped-off" product would be the complete text of the book, and that's what the publisher is trying to sell. In the case of Civ3, a patch to change the language to something else is nowhere near to being the entire product. In fact, it could be argued that the actual wording of the text is not really part of the game at all - for an example of this, does the fact that a football referee calls a game penalty in Spanish make the penalty any different than if he called it in English or used sign language? The language is not the game. Since it's the game that this outfit wants to sell (though they have a funny way of promoting it, I must say) a language patch is not a violation of "their property".

      Which brings up an interesting point. If I am paying my money for "their property", then why can't I do what I want to with it? If I pay money for any other kind of property I'm allowed to do what I choose with the product that I've purchased. Computers are about the only industry where the business revolves around "You pay for my product but I still own it."
    • Translating and distributing the first chapter of Harry Potter would only be a copyright violation if you were selling it. Otherwise there's a pretty clear case for fair use.

      However, software is treated differently. Bad analogy, but still a valid point if they're actually distributed a full translated copy of Civ3. If they're just distributing a patch, as some have said, than I'd say that puts infogrames on shaky ground unless France has a DMCA-type law that prevents reverse-engineering of any sort.

    Keeping up to date with the latest OpenSSH releases always helps, but if you want to put an end to those SSH1 attacks (which can affect OpenSSH 2 and above in some cases, and may do so again in the future), add this line to your sshd_config (in /etc or /usr/local/etc):

My (minimal) survey seems to indicate that this is construed as a "feature". what's up?

        If you have known incoming IP's, I believe adding them to /etc/hosts fixes the problem. Complaing to your ISP may help, but if your ISP's DNS admin has a clue, he'll probably point out that this is a really stupid test to be performed to begin with so he doesn't consider it a high priority to fix things on his end so it'll work, but he may get around to it eventually...

        Uhm, you're kind of confused. The main ssh packages in Debian are:
        • ssh [openssh.com] - OpenSSH port of BSD's version of ssh that branched off the last free version of ssh put out by ssh's original developers. It has supported ssh protocol version 2 since roughly August of 2000, and versions supporting ssh2 made it into Debian soon there after. Currently version 3.01p is in Debian, and I think its pretty much equivalent to to the non-free ssh3.
        • ssh-nonfree [ssh.com] - non-free version of ssh from its original developers. It only supports ssh protocol version 1.
        • ssh2 - Version of ssh supporting ssh protocol 2 from the makers of ssh-nonfree. License is more restrictive than ssh-nonfree's license.
        • ssh3 - As far as i can tell its not packaged yet. Is the license more restrictive than ssh3? Regardless, there is no ssh protocol version 3.
        Anyway, Debian has had ssh protocol version 2 support for a long time,.
      • Answering everyone at once, when I do "apt-get update; apt-get upgrade" I still get (open)ssh 1.2.3.

        Installing "unstable" is *not* an option at many (most?) sites. You install an unstable package on a live server, you die. Or at least you lose all root access on the live servers. The problem isn't any single unstable package, it's their tendency to pull in other unstable packages. This can get out of control real fast.

        Even installing from pool is problematic, but usually acceptable since you're compiling it locally and can avoid creeping dependencies... but some Debian tools require Perl 5.5 which breaks stable systems. If you're willing to devote a system to unstable, you might be able to create an installable package... but this is not something Joe User is going to be able to do.

        So I stand by my point. If you require SSH protocol 2 (supported by OpenSSH 2.x and 3.x), you will knock out most Debian users until either Woody is released or somebody takes a honking big clue-stick at the appropriate Debian maintainers and openssh 2.x is released as a Potato security bug-fix.

      Only OpenSSH versions prior to 2.3.0 are vulnerable. OS X 10.1 uses 2.9p2; IIRC no version of OS X which included OpenSSH was EVER vulnerable to begin with. So, you can of course turn off ssh 1 if you desire, but you need not do so because of this exploit.

Six months later CERT mentioned ssh1 exploits picking up, but by then a person can lose track of which version is safe.

I don't have Civ III (yet), but Civ II was purposely designed so that it could be easily modified by fans. It also included a map editor - I can't imagine that Civ III is any different, but perhaps an owner of the game would like to comment.

    Things like rulesets were laid out in simple configuration text files, so that patches could be applied to change the nature and look of the game - right down to individual units and map squares. Civ: CTP 2 (a game I own) also has easily moddable rulesets (the game is so buggy you simply MUST install Apolyton's patch).

    Beating down on fans and modding is stupid , the most successful games are those that have been modded (Halflife, StarCraft). Until I see firm evidence of something other than this translation case, I still want Civ III and will enjoy playing it.

    • That's interesting, especially when you consider that the Bush campaign ran IIS. Of course they probably just inherited the contract for the Whitehouse server from the previous admin. It's hosted by Akamai, so it's possible that the administration didn't make any decision about the OS at all.

      As for the Queen, well... she traded in her fancy Sparc hardware for x86 boxes and got tired of Linux. So, if you are in that situation and you want something that's nothing like Linux, what do you choose? Windows.

      That in itself is interesting--if people dump Sparc hardware for Linux x86 boxes and then sour on the OS, what will they do? Install Windows.

      So, once again, commercial *NIX vendors are the biggest losers to Linux, not MS.
