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

low Nessus Plugin ID 70232

Language:

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.
