Do you live under a rock? There were a lot of public announcements 
about this.

Yes.  There was a presentation at Blackhat Europe about this.  It 
happens all the time.  Vendors do not practice responsible 
disclosure but they expect you to.

So in one sentence you say that the ISS bug is only a DoS and now 
you are crying that a bug is being handled irresponsibly?  Don't 
you have already talked to death DNS attacks to sound the alarm 
about?

So if in the best of your abilities this is only a DoS ---> why cry 

over so called irresponsible disclosure of a bug?  Oh wait, the 
minor memory leak that you think you found is the issue.

So what would you have done?  What smoke-screen are you talking 
about?

You got that right.  We would all love you to get some insight.

Obviously.  I mean if *you* couldn't figure out how to exploit the 
ISS issue then they must have failed.  Or wait, you couldn't figure 

it out so perhaps they failed but are still smarter than you.

So after 30 minutes you were wrong about an issue.  Tell me again 
how smart you are.

>Not to mention the silently patched memory leak.

Alert the press.  DNS is can be attacked AND there is a memory leak 

in Sendmail.

Nah the 1337 h4x0rs will be too busy going after DNS right?

Yeah, that will work.  Because, no offense Mark Dowd, no one else 
could have found the problem.  Well at least we know that the world 

is safe from you.

So if you find a bug, it should be fixed and released on the same 
day you find it.  Yeah right.

> It took Sendmail a mounth to fix this. A mounth.

A whole month?  The horror!  Babies will die and our women will 
raped if vendors continue to take an entire month to address as 
many issues addressed in the Sendmail patch.

> A mounth!

Mounth?  So first you say no details should have been released for 
at least 2 years and now you are crying because it took a month to 
come up with a patch.  Do you even read the shit that seems to flow 

from your brain to your keyboard?

WTF are you talking about?  The bug has been disclosed.  The patch 
released.  Why are you complaining?  How was Sendmail irresponsible 

by fixing an issue and releasing a patch?  I think you have lost 
your meds.

Except for you right?  Answer your phone.  Its the kettle calling.  

Speaking of pot perhaps you should smoke less before sending emails 

to lists.  Have you not shouted about DNS have you not shouted in 
this tripe filled email about how irresponsible Sendmail and ISS 
are because the issue is so dangerous and that Sendmail and ISS 
should watch the mass exploitation that their evil ways will cause?

One could hope that someone will take away your ability to send 
email and post to lame websites but we are not that lucky.

Grrrrr.  I am so very angry that you cannot form one sentence 
without contradicting yourself.  Grrrrr

Open source is no more reliable than anything else.  I think it is 
safe to assume that both Sendmail and ISS have a lot of experience 
in dealing with security issues.

How is working with a vendor to get a patch released not 
responsble?  How is getting a fix into a package in 30 days not 
responsible?

Perhaps you should spend more time jerking to porn and less time 
worrying about things you obviously do not understand.  Just a 
suggestion.

So are you saying Apache has never taken more than 30 days to patch 

an issue?

I am sure the readers of this and every other mailing list you are 
going to post this crap to will be sitting on the end of their 
seats awaiting your next insightful, intelligent, and as always 
100% correct post.
