Amazon Linux AMI : kernel (ALAS-2012-118)

low Nessus Plugin ID 69608

Language:

Synopsis

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

Description

The rds_recvmsg function in net/rds/recv.c in the Linux kernel before 3.0.44 does not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a (1) recvfrom or (2) recvmsg system call on an RDS socket.

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.
