Urgent Ubuntu security notice

This will only apply to Ubuntu users (server or desktop). Anyone who's not one can probably look away now.

An urgent Ubuntu Security Notice, USN-612-1, has just been put out. The full notice is here.

An extract of the salient details:

A weakness has been discovered in the random number generator used by OpenSSL on Debian and Ubuntu systems. As a result of this weakness, certain encryption keys are much more common than they should be, such that an attacker could guess the key through a brute-force attack given minimal knowledge of the system. This particularly affects the use of encryption keys in OpenSSH, OpenVPN and SSL certificates.

So, update and upgrade your systems now and regenerate your key pairs.

About

Graham Binns is a writer, photographer, musician and software developer from Lancaster, England, with far too much hair, a penchant for odd t-shirts and a magnificent hat. He has been making things up for as long as he can remember and has been making code work for long enough to make a living from it.

He has written one novel, which is in the process of composting, and is working remembering how to write before embarking on a second. In the meantime, he photographs things, since it's easier not to have to make the world up in his head all of the time.
