Linux bitten by second severe vulnerability in as many weeks

Linux users have been bitten by yet another vulnerability that gives containers and untrusted users the ability to gain root access, marking the second time in as many weeks that a severe threat has caught defenders off guard. The threat, known as Dirty Frag, allows low-privilege users, including those using virtual machines, to gain root control of servers. Attacks are particularly suitable in shared environments, where a server is used by multiple parties.
