A newly discovered flaw in Linux could mean security issues for tens of millions of users. While you only find Linux running on about 2% of home computers, the OS is very popular for business servers and it’s the basis of Android, the most popular mobile operating system.
It was discovered by the research team at Perception Point Security . According to the company, it affects tens of millions of Linux PCs and servers and the majority of Android devices (anything Kit-Kat or later). It looks as if the bug dates back to 2012. It would allow an attacker to extract security data from the operating system and execute code at the most basic level of the operating system.
There’s not much a user can do to either prevent or respond to flaws like this. Patches are being made available to some Linux systems already and more will follow. These will have to be applied on an individual bases to your Linux-based system. No word yet on any updates for Android systems. Those updates would need to come from each individual manufacturer.
As always, it’s important to install any security patches for whatever operating system you’re using.
