Amazon Linux AMI : kernel (ALAS-2013-228)

This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

The ipv6_create_tempaddr function in net/ipv6/addrconf.c in the Linux
kernel through 3.8 does not properly handle problems with the
generation of IPv6 temporary addresses, which allows remote attackers
to cause a denial of service (excessive retries and address-generation
outage), and consequently obtain sensitive information, via ICMPv6
Router Advertisement (RA) messages.

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.

Risk factor :

Low / CVSS Base Score : 3.2
