Amazon Linux AMI : kernel (ALAS-2012-34)

medium Nessus Plugin ID 69641

Language:

Synopsis

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

Description

The Linux kernel before 3.2.2 does not properly restrict SG_IO ioctl calls, which allows local users to bypass intended restrictions on disk read and write operations by sending a SCSI command to (1) a partition block device or (2) an LVM volume.

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.
