Half-Life Vulnerabilities Exposed, Patched 36

Posted by simoniker from the publicized-then-fixed dept.
AEton writes "PivX Solutions revealed in a press release three apparently new vulnerabilities in Half-Life and its related mods (such as Counter-Strike and Day of Defeat). Security researcher Auriemma Luigi discovered the flaws, reported them to Valve, and waited over three months for an official response before releasing an unofficial patch to correct the issues. Details on each of the vulnerabilities and sample code are linked to in the press release. (The third one looks kind of flaky, but the buffer overflows seem real.)" Thanks to an anonymous reader for pointing out Valve have now released a dedicated Windows server patch and dedicated Linux server patch (links via Fileshack) which seem to fix the issues.

    I'm appalled that it apparently took a public release to get them to patch the servers. It would have been trivial for Valve to slide this into a patch and release it to everyone.

    What possible rationale do they have for not fixing it in <b>3 months</b>?

      money.

      It's not as though these patches will help them fix more copies of half life, or even half life 2.

      Being a little less cynical, I hope the reason was because they don't really have security people in house, and thus didn't understand the implications from some random guy as they were busy working on HL2....

      Unfortunately, I suspect it was money.

      Hmmm. Maybe they were busy working on Half-Life 2? ;)

      Seriously, though: considering Half-Life's age, I find it amazing it got patched at all! Half was released at the end of 1998, making it almost 5 years old. I can't think of many other games (or even applications, for that matter) that still get support after such a length of time.

      When a way was found to delete other people's characters in Sega's Phantasy Star Online, the company tried to patch it, while keeping it a secret (and so not explaining how to avoid this abuse).

    They still haven't fixed VAC (valve anti-cheat) so wine users can play Half-Life. This doesn't stop them from assuming Linux fans will host their games via dedicated servers though. I'm still a little pissed off that they think Linux is good enough to host their games but not worthy of a client. This is just more of the same old excellent community support from Valve.

      Most Windows-only games have Linux servers - the added stability is beneficial for a server (and most rent-a-server places have Linux, anyways) but not necessary for just the game client.

      I imagine it's substantially easier to code a cross-platform server than it is to code a similar client.
      • "I imagine it's substantially easier to code a cross-platform server than it is to code a similar client"

        Almost certainly, I'd say; most game clients are making DirectX calls these days (even when they can use OpenGL rather than Direct3D most games use the DirectX sound and control calls). Servers, by definition, aren't having to render any 3D, and so the main area of Windows dependence is removed.

      "They still haven't fixed VAC (valve anti-cheat) so wine users can play Half-Life."

      And why should they burn money supporting a niche customer base which either 1) won't pay for software or 2) already has a copy of the windows version of a game that is OVER FIVE YEARS OLD? There are like, 3 people that play half life through wine.

      "This doesn't stop them from assuming Linux fans will host their games via dedicated servers though. I'm still a little pissed off that they think Linux is good enough to host their games but not worthy of a client."

      They don't assume shit. Linux is a popular server operating system that is run by MANY hosting services, so naturally they would port the dedicated server to linux. The dedicated server is much easier to port than the full blown client with graphics (duh).

      "This is just more of the same old excellent community support from Valve."

      Let's see:

      * publish half life sdk with tools, source, and documentation
      * maintain strong mod community relationships with valve-erc website
      * support popular mods: socially, technically, financially, etc.
      * listen to the incessent bitching of every kiddie who wants something for nothing

      Yeah, I'd say it is excellent support. Quityerbitchin.

        My problem is that Valve thinks it's cool for me to run a server for their game even though I can't play it. That bugs me. I can respect that the financial decision to make a client might not be a great idea today, but there was certainly a time when it would have made sense. I, along with many others, would happily pay for a Linux client. I never once said they should do it for free. I don't expect things like that from game companies. As far as fixing wine, that might take a precious hour or two away from their team. Or they could have told people roughly how VAC would work client-side so the wine team and contributors could work around it.

        As far as your other points, I think you need to sit back and take a look at just what you're defending. The SDK was cool, fine, but the financial support was simply good business. I have no doubt that they've made far more money from CS, DOD, etc. than they've given in financial support. The mod community has contributed significantly to the success of Half-Life.

        Valve has set up a very complex network of mod developers to make money off of. I don't think you have the tools to realize it at this point, but you're being strung around like some corporate fanboy tool. Valve has very carefully crafted themselves in this we're-just-like-you-gamers image. In turn, they receive untold amount of defense from almost all of their fans. I hate to tell you this, but Valve honestly doesn't care about you or the mod community. As long as it's profitable, they'll continue on as they have been. This isn't necessarily wrong, mind you, but I see no reason for you to champion them as this gracious benefactor to the gaming industry. In reality, they're a business out to make money.

        Even though I'm complaining about Valve, this argument could be applied to almost any big game company. I've just been dissapointed in the way things have been turning out lately. Games are watered-down to be "accessible" to as many people as possible. Slick advertisements and clever lures get massive amounts of people to pre-order games they haven't even played. Corporate branding creates legions of blind fanboys running about the 'net exalting their favorite companies. I'm not asking for anything too big here. I'd just like to see a few more companies that genuinely care about their fans and strive for positive long-term relationships and not this short-term profitability. Valve could have been one of them. Unfortunately, success killed them.

          From a purely financial standpoint:
          - Any game that relies on someone other than the developer to setup servers NEEDS linux server software. There's simply no way around

      Uh... yeah... right. I'm sure it has absolutely nothing to do with the minor point that a rather large percentage of co-lo/hosted systems are running Linux, and that having a server available for said systems dramatically increases the number of potential dedicated servers.

        Half-Life doesn't use DX9; it uses DX6. Furthermore, the game has a very complete OpenGL renderer. Porting it would still take some work, I'm sure, but it's not like they would have to re-write it. And for the record, I'm neither "inanely biased" or "out of touch with reality". I simply have the rare and mystical ability to see through the PR hype and their "community support." But who cares, eh? Pretty movies make all ok.

          The OpenGL renderer takes care of graphics (and their OpenGL renderer has always been better than their Direct3D renderer in HL anyway), assuming that the game can be brought up under Linux to the point of using the renderer in the first place, but then you have the i/o and sound systems (the sound definitely us

      • Valve periodically updates their VAC system to catch new cheats. Sometimes it breaks compatibility. This time it did, and they haven't fixed it or even said anything about it for a couple of weeks. Here's a relevent quote posted a couple of days ago from the transgaming forums from one of the WineX devs:

        "Due to a recent Valve-Anti-Cheat (VAC) update WineX users cannot currently play Half-Life online. We are investigating the reasons for this are working on a solution."

  • Despite comments made by others saying that it took too long to patch these holes, I am actually glad they weren't putting resources into this. The entire HL team is probably working really hard on HL2, and I want it to stay that way. If letting HL die is the price we must pay to get HL2 out the door on Sept. 30 (in recent proximity to my birthday), then so be it.

    For the record: I still play HL and CounterStrike online. And I use Wine to do it. Do I care that there isn't a Linux client? NOPE! Why?
    • Last I heard, the HL2 and HL patch teams were made up of different people. They released a boatload of HL patches in the time they've spent making HL2, not to mention the level of work that went into some of those HL patches.

    When I saw the news on Bugtrack, i posted the information on planethalflife forums and a few other places. Was rather surprised that nobody posted it on the HL forums.

    And all those "HL is old" posts, "let it die", are posted by morons. CompuUSA has HL selling for 45 bux for the entire collection. They are selling the collections and still making money! The Mods alone make the HL series worth the money. Day of defeat just came out, and it rocks, the mod even made its own release like CounterStrike.

    Gamespy reports that 27,000+ HL servers are running, compare that to Tribes at 700. The game is STILL selling, no reason not to patch an active cash cow. I respect Valve for supporting us, after a bad experience on Tribes2 support, Sierra needs some good karma.

    BTW, Natural Selection HL mod rocks. Too bad its not well known. (Think AVP+Tribes+CC+WC3)
    • Forgot to mention, even on Driver support forums for the ATI and Nvidia gfx boards, people said they should drop support for Halflife because its old and unsupported.

      I'm glad they didnt, 1600x1200 CS with 6xAA,8XAF and high poly skins, the game looks perfect. Cant wait to see CS2 or CS ported to the new HL engine. Different engines, so CS ported to HL2 might look better than CS2. (Did you get that?)
