Amazon Linux AMI : kernel (ALAS-2012-122)

low Nessus Plugin ID 69612

Language:

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.

Solution

Run 'yum update kernel' to update your system. You will need to reboot your system in order for the new kernel to be running.
