Amazon Linux AMI : kernel (ALAS-2014-317)

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


Synopsis :

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

Description :

The sctp_sf_do_5_1D_ce function in net/sctp/sm_statefuns.c in the
Linux kernel through 3.13.6 does not validate certain auth_enable and
auth_capable fields before making an sctp_sf_authenticate call, which
allows remote attackers to cause a denial of service (NULL pointer
dereference and system crash) via an SCTP handshake with a modified
INIT chunk and a crafted AUTH chunk before a COOKIE_ECHO chunk.

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.
