Amazon Linux AMI : yum (ALAS-2014-315)

medium Nessus Plugin ID 73234

Synopsis

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

Description

The installUpdates function in yum-cron/yum-cron.py in yum 3.4.3 and earlier does not properly check the return value of the sigCheckPkg function, which allows remote attackers to bypass the RMP package signing restriction via an unsigned package.

Solution

Run 'yum update yum' to update your system.
