Amazon Linux AMI : kernel (ALAS-2014-363)
High Nessus Plugin ID 78306
SynopsisThe remote Amazon Linux AMI host is missing a security update.
DescriptionThe futex_requeue function in kernel/futex.c in the Linux kernel through 3.14.5 does not ensure that calls have two different futex addresses, which allows local users to gain privileges via a crafted FUTEX_REQUEUE command that facilitates unsafe waiter modification.
SolutionRun 'yum update kernel' to update your system. You will need to reboot your system in order for the new kernel to be running.
