I have a few ubuntu servers. When I do a "check for heartbleed" check with various tools, it says they are not vulnerable. However, these servers were installed 6 months ago and not updated for at least 2 months. How can they not be vulnerable?

As I understand 13.04 is just as vulnerable, but not mentioned in that security notice because it is unsupported (end of life).

13.04 is vulnerable, just out of the support period of ubuntu (decreased from 18 months down to 6 months in 2013) - basically out of luck, either use a ppa, or upgrade to 13.10

Well, with the exploits for this vulnerability now showing up everywhere i almost feel bad for the people that still have not-patched servers lying around.

Feel no pity whatsoever for the sysadmins. Feel pity for the users, who are unwittingly using a vulnerable service.

I am not an expert on the topic by any means, but one possibility is that older versions of impacted software are simply not vulnerable.

Ok, so I am rewarded for not having an up-to-date system. How about that...

You might want to rely on some other tool to determine if you are vulnerable or not. Or, just fix it yourself: http://www.ansoncheunghk.info/article/3-simple-steps-update-...

I ran some of the exploits that were floating around against my own servers and against known vulnerable servers. I got nothing from mine, but lots of scary stuff from the others.

This should be a useful tool on its own, but I wrote it primarily because the pattern-matching rules for Snort are inadequate. IDS vendors won't fix their stuff until I can prove they are inadequate.

Ugh. In the old days the mantra of full-disclosure was "well, if we don't make exploit tools, then the vendors won't issue patches." And then it became "well, if we don't make exploit tools, then the sysadmins won't patch." Apparently the bar has sunk so low that people personally pushing out Snort rules on snort-users aren't actually catching all instances of the bug is the justification for releasing tools to steal private keys.

In reality, lots of people in the security community just like seeing chaos in the world, because it makes for even more news headlines and in their mind this increases the status of the security community. Then it's time for the post hoc justifications for their behavior.

Maybe the sysadmin took a vacation. Fuck him, why should he spend time with his family?

I would imagine the motivation is less about money and more about having fun breaking stuff (and bragging rights).

I agree though. Hard to argue that this particular security issue needed any extra attention in order to get it fixed.
