Synopsis :

The remote Amazon Linux AMI host is missing a security update.

Description :

The Netlink implementation in the Linux kernel before 3.2.30 does not
properly handle messages that lack SCM_CREDENTIALS data, which might
allow local users to spoof Netlink communication via a crafted
message, as demonstrated by a message to (1) Avahi or (2)
NetworkManager.

your system in order for the new kernel to be running.
