So your solution is to give every two-bit idiot | that doesn't have the brains to be a cracker, but enough brains to read | and be dangerous a sure-fire way of becoming 'root' on your system? How | many crackers do you think there are in the world? How many cracker- | wannabe's are there? I'll bet you everything I own that the second group | is larger than the first. Right now my entire consulting organization, both locations, if off the net because we use SCO servers as gateways and have no way to evaluate the danger. We will probably be back up on another operating system this weekend. The fact that the novice crackers don't have the information doesn't bother me, *I* have no idea if this depends on nothing but access to the login command, or if other holes must be left open, as well. There's enough information for the crackers to know where to start, without me knowing the nature or magnitude of the risk. | | And, not everyone who would be tempted to try this trick to login as 'root' | is subscribed to mailing lists and/or BBS's. There are quite a few | people in the world, however, that would be more than happy to try something | like this if they were handed the solution on a silver platter, whether | or not they have had any incliniations or desires to becoming a cracker | in the first place. Once the word is out that there is a hole in SCO, the expertise of the people having the information is not the issue, the risk to the system is. Unless I can find this info on a cracker BBS somewhere (and I don't even have a starting place at the moment), our SCO systems are going to be off the air, or on their own net feed. No, I don't intend to use a patch (if available) which is labeled "this fixes a security hole but we won't tell you what it was or how to test that you have it now and don't have it after this patch is applied." Does this mean SCO will have to get their system C2 rated all over again? -- Bill Davidsen (davidsen@tmr.com) UNIX Codger Will solve problems for money. Stupidity, like virtue, is its own reward.
