Ubuntu & Gentoo Servers compromised

The case of the Ubuntu servers being breached [wiki.ubuntu.com]
Missing security updates and system administrators not running updates on servers is a problem. I don’t know why they didn’t do any updates past Breezy. They suggest that it was because of problems with network cards and later kernels but I don’t get it. Since when do software updates for an operating system have anything to do with what kernel is running? If there is a problem with hardware support for the network card you have two choices. The first is to fix the driver yourself or pay some one to do it. The second is to replace the network card to a better supported device. Both situations could be costly but it would get the problem fixed and five of the servers wouldn’t have been taken down at the same time.
If the kernels were configured correctly, the boxes probably wouldn’t of even had to have been rebooted.
Running FTP instead of a more secure version is not so bad unless they were running accounts with higher privileges than guest or using system accounts. In which case thats just stupid.

The Gentoo Situation [bugs.gentoo.org]
Apparently there is a problem in the packages.gentoo.org script. The bugzilla article goes into deeper explanation but basically there is some pretty unsafe code which could have allowed any one to run any command. I understand that the code is old but it probably should have been audited at some point. The problem would have stuck out like a soar thumb if looked at by a python coder and they probably would have fixed it, or at least suggested a fix. The problem was found on Tuesday the 7th. All of the infra- (I assume they mean infrastructure?) guys were at a conference last week so they couldn’t work on it. It still seems that if they were at the conference until midnight on the 12th they would still have been able to put up a coming back soon placeholder on the packages site by now. Hey, if they put some pay per click ads up there maybe they will get some additional funds during the down time. I would like to see what products would be pushed thru the advertising on that one. I believe that they could have reduced the downtime by releasing the code for the packages.gentoo.org site as open source or by asking for help from developers to review and upgrade the code as needed.

Its not strange for web servers get hacked. They get hacked all the time but who’s fault is it in the open source community? I really think that there is a problem in the community when it comes to situations like this but the blame can’t be placed on any one person. I would offer any assistance I could into getting these situations resolved but its not as easy as that. There has to be a certain level of trust for those working within a project. If they gave out keys to their servers to anyone the servers probably would have been compromised a long time ago. I hope that the affected sites can pull them selfs together and get back up and running as normal. It seems that Ubuntu did not have complete down time, but the Gentoo site is still down and there is no indication of when it will be back up.
