Amazon Linux AMI : kernel (ALAS-2016-757) (Dirty COW)
High Nessus Plugin ID 94182
SynopsisThe remote Amazon Linux AMI host is missing a security update.
DescriptionA race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.
(Updated 2016-11-10: This advisory was upgraded to Critical.)
SolutionRun 'yum update kernel' to update your system. You will need to reboot your system in order for the new kernel to be running.
