Linux warning; Debian/Ubuntu and other linux installations are in extreme risk as a very serious vulnerability has been discovered that can allow relatively easy bruteforcing security codes generated with the affected systems.
Truth be told I don’t know much about linux so I cant really describe what the problem is and how it may affect your setup, I do however know enough to recognize that this is a very serious issue. Actually, I used to have a Debian based VOIP server (Trixbox) up and running (guess many other are in the same situation) and the problem here is that systems like that suddenly are vulnerable.
If you have any kind of Linux installed (be that Ubuntu, Debian or just some print server in the corner office) be SURE to check the with the supplier if you have an issue and need to do some patching.
