      Full disclosure after a patch is done, yes. But doing it before serves no purpose but to conform to some wishy washy idealism and potentially amplifies the damage an exploit could cause.

      I think a timeframe needs to be established. Those who find exploits in programs have a moral obligation to let the maintainers of the program know first and give them a reasonable amount of time to fix the problem.

      But, by definition, if any of the "good guys" have found the problem, it's equally likely that any number of "bad guys" also have found the problem. With exploits in the wild. So telling everybody to be on the look-out, or even close down some services, could easily be the "Rigth Thing(tm)" to do.
      Look, for instance, on all the bad press Symantec drew for keeping info on Slammer to their own customers instead of alerting everybody.

  3. Sendmail - too flexible for most by linuxkrn · · Score: 5, Insightful

    Sendmail is a very flexible mail package...too flexible for most people.

    It's power and configuration settings make it a good choice for admins who have taken the time to read on it. However, more often then not we find that there are a lot of lazy admins out there who just get it "up and running" and don't care to understand the security issues with the server. While I've used sendmail for years in the past, but now use postfix. There are a slew of other mail programs out there that can be configured without having to use m4 rules, understand sendmail's rewrite metods etc. I would suggest that if you must have a mail server up, but don't want to take the time to learn sendmail, PLEASE, use something else. I realize this is a little off-topic but it's not too much. It all boils down to securing the net. That takes more then a few bug fixes (and YES you must apply all of them) and a good admin to configure the server/services.

  4. Improved policy? by Jeppe+Salvesen · · Score: 5, Insightful

    Wouldn't it be best to issue a statement like "sendmail has an exploitable vulnerability, we recommend that you switch to your standby alternate mail system until we release a fix"? There is no way that blackhats would figure out where to look from a statement like that, and those of us with really good security could switch to our exim-based solution if we really feared to be hacked. Basically, do we trust the homeland security dept to determine our security policy?

    That being said, good to see a well coordinated patch release. I just wish the paranoids would get advance warning.

    at this point, this does seem to be addressed.

    how do we (ahum) fix the end user? my belief is that it should be required that end users have staff/contractors that are certified on their stuff *and* that hey maintain a maintenance log that documents actions or lack of them. if you look at radio stations and the requirements they include licensed radio engineers and logs and other must-dos and must-haves.

    If I've got a vulnerable service running on on of my systems, I'd rather know about it right away so I can make the decision as to whether I want to keep it running or temporarily deploy an alternate service.

    I liked the handling of ssh's problems last year much better. "Heads up, there's a problem in these versions. We'll let you know exactly what after we get the patch out." It's not enough to give a hacker a reasonable foot up, but it gets the service off the network should anyone already be quietly taking advantage of the weakness.

    It sounds cool to have the US govt leaning on vendors to write patches, but I have a feeling that if this becomes the norm, vendors will just push DHS for longer and longer lead times. The article indicates this particular bug was known since January. Two months is a pretty long time to wait for patches!

    And this is just DHS's "first test" - I imagine after they build up a cozy relationship with the major security-problem vendors (i.e. Microsoft), they might not even disclose any known flaws until patches come out (i.e. months to "never").

    Remember that government officials will probably listen a lot more attentively to "captains of industry" (i.e. MS) than "those unwashed hippy hackers" (i.e. the open-source community).

      What's really cool is that they're leaning on admins to actually install the patch quickly.

      Sure, it sucks to be "left in the dark" while vendors slowly come up with patches. Sure, you'd like the vendor's "feet held to the fire" to write, test and release the patch as quickly as possible. If that's painful for them, well, they dman well deserve it since they wrote the but in the first place. Or at least that's how it feels to you and me, small-time admins (at least me) who find out when the patch is released weeks or even months (2 in this case) after the initial discovery. It's easy to feel this way.

      But historically, the biggest problem has not been the timeliness of releasing patches. The REAL problem has been that most admins/users do not install the patch until _after_ an attack has begun.

      Pathces not getting applied is by far the largest problem. It dwarfs the problem that of several weeks elapsing between initial discovery to patch availability to public announcment (where the "problem" is that some black-hats might have known for some time and might have been quietly exploiting systems for a long time).

      Sure, it rubs you and me the wrong way and might even hurt our feelings a bit that we were kept in the dark for 2 months. Yeah, it sucks that our servers were on-line and open to attack all that time (and long before initial discovery by ISS). But get over it.

      In the larger picture, what has always mattered much more is getting all or most systems patched. That has historically been a giant problem. Admins don't patch, for one reason or another. Some are overworked, a few might be lazy, many don't find out about the patch, and in a great many cases the admin isn't authorized to make "unnecessary" changes, or would be risking his job patching a critical system before upper management felt it was urgent.

      In the past, only a widespread attach has given most admins that sense of urgency to apply the patch. That sucks.

      The DOH using its clout to provide that sense of urgency to apply the patch before an attack begins is a good thing. To the extent they pull this off (it's still too early to judge), they'll have gone a long way towards solving the largest computer security problem.

      So whine all you like about being left in the dark. Mod me down for going against the flow here on slashdot. Complain about the extreemly unlikely chance that some black-hat knew before ISS and was quitely and undetectably exploiting the bug. But don't try to deny that by far, by at least an order of magnitude, the largest problem has been a widespread failure to apply released patches until after a highly successful and widespread attack.

      To the extent the DOH puts pressure on admins to install this patch before an attack, they will have made a huge improvement in overall security. The several weeks from initial discovery until patch availablity and security advisory just isn't significant in comparision.

    I think it reflects well on discoverers of vulnerabilities if they notify the software maintainers first by backchannel means and describe the vulnerability with enough precision for the authors to be able to fix the problem in a timely manner. DoVs should get extra credit if they submit an actual patch that fixes the vulnerability (does not apply to proprietary binary products, clearly).

    But the vulnerabiltiy is a ticking time bomb out there for users in the real world. The white hat DoV may have discovered the vulnerability after 3 black hats who are shoving it into their latest malware.

    The discoverer of the vulnerability and the maintainers of the software are jointly responsible for doing everything in their power to expedite their work, to notify users of the vulnerability, and to provide a patch for them.

    Finally, all software users have the responsibility to keep appraised of the latest security alerts and patches for vulnerabilities and to apply them.

    If any of the 3 parties: discoverer, software maintainers, software users fall short on any of these responsibilities, then all users will suffer.

    As a user, I must rely upon the goodwill of the DoVs and the maintainers.

Sure, a public announcement increases the number of crackers who know about it, but also gives me enough information to react. There is a security hole in sendmail, but no patch yet? Well, without real information, I can't confirm if my particular installation is at risk. Once I know about it, I can take reactive steps. With enough information I could try to patch the vulnerability myself. With enough information I could try to limit my risk (say, changing my sendmail configuration to limit what an attacker can get, or adding a wrapper to detect the attack and terminate the connection). With enough information I reasonably weigh the options of disabling sendmail for security reasons versus keeping it up for my users.

    With no information, I'll just keep ignorantly running the vulnerable version, possibly getting attacked by crackers who already knew about it. With a little information, I don't have enough information to decide if I'm really at risk and to weigh my possible solutions.
