Linux is well-known for its security advantages over many other operating systems, but that doesn't mean it's immune to problems.
A Linux kernel flaw first discovered earlier this month, for example, gives hackers a way to not just gain root privileges in 64-bit Linux operating systems but also to leave a "back door" open for further exploitation later.
