Amazon Linux AMI : openmpi (ALAS-2013-256)

medium Nessus Plugin ID 71396

Language:

Synopsis

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

Description

A flaw was found in the way ibutils handled temporary files. A local attacker could use this flaw to cause arbitrary files to be overwritten as the root user via a symbolic link attack.

It was discovered that librdmacm used a static port to connect to the ib_acm service. A local attacker able to run a specially crafted ib_acm service on that port could use this flaw to provide incorrect address resolution information to librmdacm applications.

Solution

Run 'yum update openmpi' to update your system.
