Amazon Linux AMI : ruby20 (ALAS-2014-441)

medium Nessus Plugin ID 78874


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


The REXML parser in Ruby 1.9.x before 1.9.3-p550, 2.0.x before 2.0.0-p594, and 2.1.x before 2.1.4 allows remote attackers to cause a denial of service (memory consumption) via a crafted XML document, aka an XML Entity Expansion (XEE) attack.


Run 'yum update ruby20' to update your system.
