On Tuesday, January 19th, 2016 Nu.nl published an article (in Dutch) that a critical vulnerability in Linux was discovered which threatens PCs, servers and Android devices. Of course we have investigated immediately. Only a few 1A-servers are vulnerable and the impact is low.
Basically Linux exists of a number of components:
- The kernel. This component is responsible for correctly handling the hardware and communicating with the operating system.
- The operating system, also called “distribution” in Linux. This contains all the basic software.
- Applications. These provide the functionality of the system (such as a Web server).
This vulnerability and 1A-servers
This vulnerability affects kernels from version 3.8 and up. Most 1A-servers use kernel 3.4 and are therefore not vulnerable.
A few 1A-servers do have a newer kernel because they have newer hardware. But the vulnerability is a so-called local exploit. This requires local access to the 1A-server to be able to abuse it. So the probability of abuse is small because only employees have access to the 1A-server and specialist technical knowledge is required to actually abuse it. Nonetheless we will still fix this vulnerability in the coming month.
